We have put 74,000 miles in 16 years and have yet to pop a tile or any other flooring piece. Something may be wrong with that particular coach?
I did drag the trailer hitch in a 270 degree curve while towing on Hwy 1 below Fort Bragg, Ca. No adverse effects except momentary shock to the driver.
The normal ride height of the CC Magna and Affinity of that era is low which is part of their good looking profile.
These rigs would likely get high centered while using them for off-roading.
