Seat belts in a camper?

One solution I considered is adding seat-belts in the camper itself for the teens. I know class C RVs will do this but I don't think I have ever heard of it being done in a camper. Safety and keeping the kids buckled in is concern of course but pushing that aside for the discussion, is there any legal issues with the idea?

Well, it is legal in most states and as far as safety,I think the TC mounted on the truck correctly would handle a collision better than a Class C or Class A motorhome..The motorhomes are built on the frames but a TC sits anchored in a pickup..Way less likely to crumble on a pickup than a motorhome..I just sold a Class C 21ft with seat belts..

My Class C was way more prone to leaks and cracks being built off the frame and the unit itself had to absorb every little twist and turn while on a TC,the pickup absorbs all those twist and turns,not the TC..

There is a reason it is legal in most states,it doesn't provide anymore risk than a motorhome or they would ban it in a heart beat like everything else they ban..Motorcycle helmets required comes to mind.

People around here ride around in the back of pickup trucks all the time and about every other pickup has a dog in the back bouncing around..lol
