Are "all-bed" campers length safe? Most compatible all bed?

@camper8251 :) thanks for the encouragement! Im definitely excited to go on adventures in my van. I'm a young guy but Im getting too old to sleep in my SUV anymore. My biggest fear is if my car breaks down I'd like to be able to pretty much buy any used 1 ton pickup truck in whatever town I am in and be able to carry my camper. I only want to put in big money to either a camper or a car but not both.
