We went to Wyoming this month for vacation. On a typical trip to Wyoming we would see maybe 5 truck campers the entire trip. This has been the case for the last 20 years. This year we lost count. ...
I live in Colorado but go out east to visit family twice year and you don't see as many truck campers as you do out west. I think one reason is that TCs are used for mostly dry camping out in the wilderness and staying overnight in rest areas. Rest areas out east are much noisier and not as safe and unless you want to go way up north to Maine there isn't as much space for dry camping.
Every year I see more and more TCs here in Colorado.
