I always saw the downside of truck campers and vehicles mounted RTTs to be the fact that if you want to go wheeling, you have to pack up and stow EVERYTHING good and secure, and if you flip over, (bigger concern with the higher COG), not only is your truck wrecked, but your accommodation are too.
That said, your style of overhanging has a lot to do with your choice in accommodation. If I were to pick between a truck camper and a RTT, the camper would take it hands down.
In my Flippac try to secure my stuff as best as I can. Simple forest service roads can josstle stuff about quite a bit. I'm actually more concerned about some bozo doing something idiotic on a highway & causing a crash, all the more reason to secure gear.
