Choosing a camper for compatibility (short and long bed)

It's true. Of all the van life/RV life options though, truck campers just seem to me my best bet and if I'm willing to lose 25k on a used truck, I should also be willing to lose 25k-30k on a camper. Hopefully, none of them break or at least just one. But I'm going to look at Host. I saw Venture America came out with a carbon fiber travel trailer. I don't want a travel trailer but Im hoping we get lighter and lighter materials in the next 10-15 years.
