The big problem is that the TT/5er suspension is designed on the assumption the vehicle won't be occupied. Springs are selected for stability rather than ride comfort and damping is set up to keep the thing on the road, rather than to provide a comfortable ride.
Certainly, you need 2-way communication with the tow vehicle.
Ride quality is the primary issue that has us in a Class A, despite many relatives who have bumper-pull trailers and think we're nuts.
