Watch me test my camper build 4Runner up Lytle Creek. The rutted areas towards the end of the trail are very deep and require a lot of clearance and suspension travel. I can assure you that the rutted areas are deeper than they look.
My 4Runner is a Trail Edition 4x4, on Billsteins 1500's, Nitto Ridge Grappler's (33's), a 2-inch lift, and no lockers. My frame kept getting caught in the middle of the one of the ruts. After trying ATRAC and 4Lo, I decided it was time to have my buddy pull me up.
My rig was built to be a camper for my wife and family. Hence, why I am lugging around a 200-pound RTT and a trash bag lol. She is not built for rock crawling and technical terrain. However, I do enjoy trying local trails from time to time.
I say all this because I continue to hear people saying that you can do this trail in 2WD. This is completely inaccurate. Always bring a friend and have offroad supplies ready. Never go alone!
I hope you have a great time no matter what type of vehicle platform you choose to drive!
