    This is a great video! Thank you so much for sharing, I'm planning to go full-time Rving but will need to stay in the Northeast for a while, with our cold winters this is a great way to keep in the heat. I really appreciate all the details and the step by step instructions, you've got me believing and I can do this myself. 😀

    Great step by step video on the insulating of your under belly. One recommendation though is put tank heater (blanket/pads) on your rig. I like that you posted this, I am currently doing similar to my thunderbolt 5th wheel. The rv plant didn't do a good job putting it together. They had water lines crimped underneath the rig. The waterlines below the insulation and not wrapped. So they froze while up in Montana. So far I've wrapped the water lines with the insulation and put All of the waterlines above the insulation between the floor and the insulation. Love your video. Going back underneath to add the bubble insulation as well. Thank you

    Great vid. Your materials & method is what I'd figured would be the way to do it. Basically a sandwich of: tank, flex foil insulation or EPS/XPS rigid foam, Coroplast. Spray foam for big gaps like black/gray valves. To add air sealing, I'm thinking a bead of caulk/sealant between frame & Coroplast seams.

    A couple of notes for whatever they might be worth... Insulating the tanks won't protect your dump valves, so your potential for problems there in any sub-freezing temperatures is still high. The poorly engineered units which have this protection from the RV manufacturers, meaning they are best-in-class in that quality-troubled industry, will typically have the valves up right next to the tanks in the insulated area with the handles sticking out. The killer custom-engineered units that can actually withstand Alaska / northern Canada / Scandinavian cold rather than just having RV marketing materials that pretend they can (e.g., Nord Euro Mobile's units) will have any tanks and valves up within the heated envelope of the trailer itself with only the dump pipe plumbed through foamed-in insulation to the outside. These companies also don't use foam board insulation anywhere on the outside or exposed to the outside, and especially directly underneath. The reason is that, despite the "insect resistant" stated on the facing, the reason that statement is even there is because the stuff tends to be tunneled into by insects, and ants in particular. If you are parked anywhere for any length of time and they discover access to it, you may find it eaten away or hollowed out in sections.

    Thank you for your input, I agree 100%. Just to be clear this install was not to make my trailer a true four season trailer (or full-time), but to just help extend it into the colder seasons. When I purchased my current trailer, I made sure it came with insulated and heated tanks (to include dump valves). Obviously I'm sure the so called "arctic package" that it comes with is nowhere near the level that would be needed to live in Alaska/Canada year round, but it's doing well here in Washington so far as a part-time used RV. Plus when you get into those constant low temps, you better have a good plan for your exterior water source and invested into skirting your RV.

    @@thelosttexan1912 Yes, my concern is that viewers may think that doing this project will "extend" their season into some freezing temperatures, but the uninsulated valves will not allow for that, and along with no heat source to the tanks, those are the main differences between a cold-season or "arctic" (false impression) package from RV manufacturers and their regular products. It's a much bigger job to try to retrofit all that, and even then with an R value of only 4 to 7 around the tanks and valves, it's very limited protection. That's also the reason the skirting becomes important. The first custom cargo trailer for actual arctic purposes that I saw never used skirting and the water fill was straightforward: a hose was kept in a heated storage compartment and when fresh water was needed, it was pulled out, connected to a frost-free hydrant and the internal tank was filled in just a few minutes and the hose disconnected while the water was still running, the hose drained, and put back in the heated compartment. (It never had a chance to freeze while the water was flowing.) Even though it was far more efficient than virtually any RV, one thing that still had to be guaranteed was energy to run the systems, from shore power, generator, solar, or usually a combination of them so there was always a backup source. That unit had dual small propane heaters (intake/exhaust plumbed to the outside), warmed radiant flooring, the inside walls were thermally broken from the trailer's thick insulated framing, and it could operate continuously in comfort at -40 to -50 degs. F. without skirting or doing anything extra for it. Those are the best RV's in my book, not the ones with all the fancy aesthetics. My "four-season" RV built in Oregon uses a ton of energy and is still quite uncomfortable and struggling to stay thawed if it's anywhere near 0 degs. F outside. They aren't really "four-season" comfortably even in much of the lower 48.

    I used a little square of the underbelly material under my fender washer so the washer wasn’t crushing directly on the actual underbelly….I would trim the foam , maybe an inch or so away from the underbelly… leaving enough to lock it in , but not having all the extra that’s doing nothing but possibly catching dirt.. I would paint mine like yours… I’m also caulking all my edges so no water makes it’s way into the channels of the underbelly..

    I'm not sure exactly what you're referring to. There should be an air gap between the Reflectix and the underside of the trailer and like wise with the R-tech. Now if you are asking as in a layer situation of both products. I think in a perfect world having multiple layers with air gaps between each product would be more beneficial, but I don't think it's as practical with the limited space you have under the trailer. The goal is to keep cold air out and warm air in, the more barrier you have between the two, the better.

    Im sure there is probably some air flow, however, any fully closed space that isn't fully filled in by way of foam, insulation etc and is therefore an air void has the ability to condense.

    I think a skirt for your trailer/rv is a great option, but it does require setup/take down with each trip in addition to storage for materials when traveling to and from camping site. I know that people who camp in extreme cold area have skirting in addition to underbelly installation/protection. In the end, I guess it just depends on what you want to do/spend/install/deal with each trip.

That being said, If it was mine and I was going to do it myself… I would probably replace the whole section of the slide floor. I would also probably replace the particle board with plywood. Plywood is more expensive, but it is stronger and holds nails/screws better. It also has a better water/heat resistance.

    Can you tell me the thickness of the coroplast? I want to order some but there's .157, .236, and .393. Also, I'm curious as to why you didn't use the r-tec all the way through. Why the shift to Reflectix?

    Ken Leek it’s 1/8th inch (what I was using). As far as not using R-tech all the way through, it was just a matter of budget at the time. I had purchased two sheets of R-tech and a roll of Reflectix. I would of had to purchase another sheet (only really needing a quarter of it) so I just used the Reflectix in the areas not directly under the tanks. Hindsight 20/20, I would of bought an extra sheet of R-tech and more rolls of Reflectix, laying a layer of Reflectix down the entire length of the trailer and then laying the R-tech on that and boxing off the tanks like I did. AND add tank/pipe electric heat pads. I didn’t have the budget at the time for it, so I used what I had to work with. That’s why I encourage people at the end of the video (part 2) to add any recommendation or what they end up doing as it may help improve what I fell short on.

    @@thelosttexan1912 Ah, well then I'm definitely glad I asked you. My fifth wheel is permanent and non moving and I live in Joshua Tree, CA. No chance of tanks freezing but the underbelly is a nightmare. I was considering using fiberglass insulation and then sealing up the underbelly with the coroplast with rtec glued on it like you did. However, in one of the comments you mention the need for airflow. Would using fiberglass insulation backfire on me?

    Ken Leek The only issue I see with fiberglass insulation is it’s lack of resistance to moisture, but if you’re in a super dry climate then maybe you’d be ok. If you were referring to the airflow of the trailer moving down the road, I was speaking as to the coroplast being installed in a way that it didn’t get caught by the force of the wind traveling under the trailer when going down the highways.

    Everything in your RV has some level of installation, the only thing that doesn't are your water tanks under your RV. So adding a barrier between the tanks and the outside elements will only help. There should be no reason it would "mess up" anything.

    Condensation inside the coach/cabin? Or in the newly enclosed underbelly? Water vapor shouldn't really exist inside an enclosed underbelly if it is air sealed. But good air sealing is hard to get done right. Lots of caulking seams & foam cans for bigger gaps.

    I didn’t while owning it. Just like anything else when using tape, make sure the area is clean and free of oily residue. Side note, anyone who owns a trailer with underbelly protection who requires warranty work/ or any service that requires the technician to work up under the trailer will have tape holding the cutout piece back up. The technician will simply cut a hole in the coroplast and work on the area and then tape it back up.

    I have to agree with you in the fact that there is no degree of accountability when it comes to the build quality of most motor homes/RV trailers. The sad thing is most people don’t learn this until after buying one even with the internet full of warnings of buying/owning a RV. I love that I purchased a trailer for our camping trips, but it was definitely an eye opener with our first trailer.

    Just a small point here-- but you aren't going to be keeping the cold out, but, rather you hopefully will keep the heat in. Basic science tells us heat energy travels from warm areas to cooler ones. So when an area gets cold it has lost its heat, not that the cold came in, unless there is a window open. But even then the warmer air would travel to try to warm the cooler air, since warmth travels from warm to cooler areas. Always!!! Why is this important? Well, it can help you focus on where to concentrate your efforts to keep a space warm. Where and what exactly you need to do to save your heat in the winter season. Since warmth travels from warm to cooler areas. And we all all very glad it works this way! Why???? Because if it didn't work like that imagine trying to heat up your frying pan to cook a few eggs for breakfast!!! Not unless heat transfers from warmer to cooler---- would your frying pan ever heat up! Would it??? The hot flames transfer heat to the cooler frying pan. If it didn't go like that, if the cool from the pan was somehow going to invade the hot flames, the pan would just get cooler and cooler--- how would you ever get the eggs to cook? How would you ever get the pan to heat up???? It never would happen, it never could happen, if the pan's coolness left to go into the hot flames. We know from experience that does NOT occur. But rather the flame's heat travels into cool pan! Right??? Think about for a few moments. So simple, yet so very powerful!!! And a trailers heat travels too. To a cooler area--- to the cooler outdoors. The cold does not come in but rather the heat leaves!!! Knowing this you now know where to concentrate your efforts to break these thermal (heat) transfer areas. To insulate them. Cover them with the correct materials to slow or stop the transfer of heat in, or out, of your living spaces, depending on if it is summer or winter. Whether you want to keep the warmth in, or out of, your spaces. Remember: heat energy always travels to cooler areas. Not the other way around! In the winter time your heated space is loosing heat, NOT gaining cold. And in the summer the heat from the outdoors is invading. It is coming in, warming up your cooler interior. So find the heat transfer points. Any work on insulating those spots. To stop or slow heat transfers. To keep the temperature more even or steady. To keep your spaces comfortable. Which is much easier to do once you know how it all works.

    LOL! True! I traded it in about a year or so ago. With three boys, it was just too small for the amount of camping we were doing. I will say it was a great "first time Rving" camper. It had enough amenities for anyone who was transitioning from tent camping to RV camping, but was still on a tight budget. At 23ft long and 7ft wide, it was short/narrow enough that traveling was easy, but the over sized slide made it extremely roomy once at the campsite (for it's size). The exposed underbelly did limit camping in colder months, but after closing it up, it made camping in the late fall/early winter months very do able.
