The downside with any pull-behind is that you're stuck in the truck for hours on end..not nearly as comfortable as a motorhome.
Have you noticed car haulers have switched from 5th wheel to conventional trailer design in order to improve hauling efficiency -- most carry 9 cars now.
On the highway they seem very stable, suggesting that with proper design a conventional trailer behind a large truck can also be stable. Granted, 5th wheels do allow for greater trailer size and weight, although downside is multi-level floor. Many also sit very high making it hard to get in and out. My parents can no longer camp with my sister because her 5th is too high to be safe for them.
