I do a type of it. Since I don’t have the coin for all that fancy stuff I stick with a ground tent, sleeping pad and what not. A couple years ago it wasn’t popular and rtt (roof top tent) were affordable, really good ones that is.
It is quite nice getting out there and camping where no one ever is. A good channel to watch is coyote works and Mark Dorian. They both do some really great overlanding with great vid quality.
Honestly you don’t need much to do it. Sure a rtt, fridge/freezer, newest bestes off road vehicle is nice but not necessary. I’ve done all my overlanding/camping with highway tread tires on my 2000 4runner and basic camping gear with a 20 year old ice chest.
One thing I do suggest is getting extra rear weight springs for what ever you drive or all heavy springs all around, gear weighs a lot, along with water and extra gas. I’m at max heavy springs +550 lbs constant weight and they are so compressed when I’m loaded down. Got to swap over to front fzj80 landcruiser springs (sitting in garage now). Keep us updated with whatever you do!
