You can always leave it loaded and take some weight off with the camper jacks.
Don’t overthink it.
The plus of a TCs functionality is that it can be removed from the truck and the truck used separately. This is also one of the biggest downfalls of a TC is that it fits in a pickup truck bed, so it’s an extremely heavy load for a pickup and it is cramped quarters for living space.
Imo, for “most” RVers, if you’re leaving it perpetually on the truck, then you’d be better served with a class C. (Folks that need 4wd excepted, even though we all know from Jayco creek that you don’t need 4wd, lol)
