IMO the trailer suspension should be able to take anything the stock truck suspension should take. I never roll over curbs at speed, maybe crawl over them if I am turning in a tight spot and i dont think that should be enough to bend a trailing arm or spindle. they should easily be able to take a small to medium pothole at cruising speed without failing, hell that is just normal rode conditions. when I tow I CRAWL over speed bumps, like 2-3 mph...
