Intuitively, campers like this 1975 born free seems like almost the best of all worlds. No extra hitch length like a travel trailer, no 1 ton or dually requirement for large truck campers, seperatable unlike a motor home, and no bed clearance issues on rough roads like a fifth wheel. However basically the only units I can find like this are vintage. So what drawbacks am I missing that makes the industry ignore them to where they're not even a niche product? I'm certain there has to be some major cons to using something like this but I don't know what they are.
There’s no issues, as long as you go straight to the camp ground.
You have two axels a distance apart. Neither have wheels that pivot to follow turns. When you go around turns, I’m imagining it putting different forces on the wheels inside the curve vs outside.
I’ve never seen that before and I’m not young, where is that? That’s pretty different
This company sells a modern bolt-on version:

Looks like it would be easy to scrape off that back bumper on any sort of ramp.
Okay, here is my wtf
Looks like it would be hard on the wheel bearings of the rear axle. Uneven roads would make for some serious bouncing too.
