I initially had some for/aft movement of my Andersen and did have some very minor denting on my truck bed.

Yes... thats the reason all manufactures of any appliance have instructions for installation, operation and maintenance/servicing... reason for warning lables (some ignore these cause they think they know better)

Proper installation and maintenance is the key!! For example and just as important, how many Rv'ers actually check the torque on their trailer lug nuts (wheels) or even their TV on a regular basis... or even have or know what a torque wrench is? If you don't heed the warning lables or do the preventative maintenance, you become a danger to yourself and others sharing the road!
