Thank you thank you. I’m about to make a big change towards my future and was researching living full time in camper. I was mostly concerned with insulating camper to make that a feasible option. I know I can gut the interior at some point and beef that up but knowing what you can to the underbelly has given me a piece of the puzzle I didn’t have. You’re a Godsend!

Great job with this video. I really appreciate the time that you took to document and video the project. Very helpful for those of us who are looking to install underbellies on our RVs. You are creating great memories for your kids that will last forever. God Bless you.

Great job tucking around the propane lines. Thanks for sharing.

Glad the video could help! Awesome to hear you're going full time with your kids! I wish I was able to with my boys. As far as the install goes... Just please note that the materials (insulation) I used were designed to extend my cold weather season, not to handle Canadian winters all season. I'm sure you realizes this, but just wanted to say it. I'd highly recommend going with heat pads on your tanks and plumbing as well as a more heavy duty insulation. I'd also recommend a heated water hose and skirting for the camper during those seriously cold winter days. Good luck and Happy camping!

Nice job! I would add a couple of suggestions from my own experience of crawling around under a trailer. I would stuff steel wool into those underbelly penetrations before spraying in the foam to prevent rodents from chewing their way into those areas. You could use mesh as well. Also I would wear a mask while spraying that glue onto to the coroplast.

Thank you for all the help in your video!!! My husband and I are camping virgins and bought a toy hauler from a couple that was infested with bugs. After 6 weeks we are still bombing in our house, garage, cars and toy hauler. We don't even know what we are doing and can't get in there to clean and educate until the bugs are gone. The slide out has water damage on the wood underneath the underbelly. There is also water damaged wood on the inside under the sink. We started by tearing off the flooring on the inside to get rid of the bugs and that's when we discovered the rotted wood. Then when I was underneath the slideout taking pictures I looked at the underbelly and it was falling down in places. So just out of common sense I told my husband before we bomb again we need to secure the under belly just because it needed to be done and the other reason was to make sure when we are bombing that the bugs stay in there and die not run out into our garage/house. We are dealing with fleas and have 6 pets. All pets get treated regularly but we thought we had bed bugs. They are close in nature and productivity. All I can say is it has been a nightmare. Sorry for the long comment. Any suggestions or help in accordance of action would be greatly appreciated!!! Keep making videos! You really helped us!!!

Some great pointers -- I never would have thought about removing the stabilizer jacks! And undoing the propane lines is clever -- I was wondering how I could deal with the lines coming through the foam panels. If you plan to do a lot of cold weather camping, I'd recommend Ultra Heat heat cable on the thin line running from the fresh water tank to the interior of the trailer -- that line is the item most likely to freeze. The Ultra Heat cable does not draw a lot of current. Thanks again for these excellent videos.

Hey lost Texan, really enjoyed your installation videos. Smart of you to start in the back and overlap going with the wind. Just as an FYI, I think using a floor jack with a 2’ square board mounted to the jack would have helped you out quite a bit holding the larger pieces up. Thinking like a drywall installer putting up ceilings. No I am not one, just seen it done a few times. Just my opinion. Thanks again for documenting.

YOU SHOULD BE WEARING SAFETY GLASSES WHILE USEING A DRILL AND / OR WORKING UNDERNEATH A VEHICLE!!! Looks good! I was very Happy to hear you mention shingling the panels, that is a must. On the areas, where you had to splice a section of the corplas together, I would have used either a piece of aluminum flat bar stock or piece of corplas to reinforce seam. On the long seam towards the front of the rv, it looks to be sagging quit a bit. I would use a section of aluminum angle, on the top side, to eliminate the sag. also the next time you pull a section down, I would also seal the open ends of the panels with heater duct tape, to prevent water infiltration of the panel's core. Looks to be a great upgrade for your comfort inside during cooler weather. Shouldn't hurt the fuel economy either.

Sadly I can't give numbers as I didn't test the temperature before and after (I really wished I had). I only had one camping trip after it was installed before I traded it in for a larger trailer. Obviously any additional barrier between you and the outside temps is going to improve the warmth inside. I just can't say by how much. It's a low cost option, but it does require a moderate amount of labor so you have to decide if it's worth it.

What did you use for straps

You did a great job. I have a question for you. Can you please install mine? Thanks for the video.

Isn't the two little drains are your what they call low spot drain to drain water before you put antifreeze in your lines also to flush out the antifreeze? Your hot water pressure release come out from the hot water tank its self.

I know etrailer has them for a decent price. We took our camper out once with cold temps dipping into the 30's at night and had no issues with anything freezing up just using the campers cabinet vented 15k furnace.

From everything I’ve read it does. BUT depending on the insulation in the walls and roof will also play into it as well. If you don’t have a barrier between the outside elements and your plumbing then your gonna have a hard time keeping yourself warm or stuff from freezing.

I used to swim noodles around all my wiring and my propane hoses how do you think that will work I'm also the one who put the foil side of foam wrong I hadn't watched any videos there's something I wanted to do now wishing I had watched your videos

Just a thought won't your last piece come in before it freezes? If so this last piece might be a waste of time and effort.

Did you seal your propane lines too? I would have left them outside. This could be very dangerous. If you develop a leak it will fill that cavity and blow up! If it is outside and leaks it blows away instead of pooling in a container. With the rumble of the road you are asking for leaks in pipe fittings. Just be careful and something to think about. One day you could have a bomb in your underbelly waiting for a spark if you get a leak. Worst part is you might not smell it with all the sealing you've done. Otherwise, great job!!

Chris Kenniburg, I’m not sure I’m understanding your question. The propane lines run along the outside of the trailer until they are required to go up into the trailer for the heater/stove/refrigerator. All manufacturers that I have seen fill in the gaps around the lines where the propane line enters through the underbelly protection/insulation. If you’re referring to the section of the line that I disconnected to allow the install of the underbelly material, then yes I resealed it with Teflon tape and also know that connection is on the outside of the underbelly protection. I hope this helped answer your question. Thanks again!

​@@thelosttexan1912 Is the propane line above or below your bottom cover? That is the issue. I don't have my camper at home but I am almost positive the propane hoses are visible from below the camper and not hidden within the underbelly. They have a hole punched in and go up to the stove and fridge but the main lines are all visible from the outside. We all know how water connections come loose because of the bouncing around going down the road. If that happens to your propane line and it is sealed within your underbelly the fumes and propane will build up and fill the underbelly. One spark and boom!!!! If they are run on the outside and exposed then the propane blows away and you are left with an empty tank which is a much better outcome.

I think it would be so much easier to call a spray insulation company and just have them coat the underside for you. Find out where they are spraying a house and go to them and tell them where to spray. I can’t imagine that costing very much. If it’s cheap, even if it wasn’t permanent, you could have it retreated every 2-3 years.
