Has anyone here had any issues with flex of the truck bed causing cracks along weld seams or other damage to your commercial cap? I've had a few dealers tell me it happens occasionally, and ARE's warranty explicitly excludes structural failure caused during off-road driving, among other things:
"Not covered under this warranty is structural failure due to neglect, alterations, addition of equipment, abuse, accident, off-road driving, use in competitive racing, vibrations from worn or altered truck suspensions or sound equipment, or acts of nature including but not limited to tornados, hurricanes, hail, and earthquakes."
