There's plenty of posts on this forum about buying a used caravan either from a dealer or private and what to look for when you buy the caravan, but having just change the pads on my coupling hitch and only having the caravan for just over twelve months , I did not actually check the wear indicators on the coupling hitch at the time of driving away from the dealership, so before driving off just check for wear on the hitch, I do blame myself but then again you expect everything to be right, 🙂
