i have an '04 pace summit and gave little thought to the rear ramp door and how it works. i assumed it was a simple hinge but never really looked. well i looked when the door wouldnt latch and seemed to be kicked out an inch at the bottom because it was. of all the maintenance i do i never thought to look for a grease fitting on a trailer! i grease the mowers, tractor, dump beds all the time but never thought about the ramp door. well the hinge rusted up over the winter and the door snapped the metal where the door is welded to it. luckily there are 3 hinges so it still works and she'll be fixed soon. Just figured id let my mistake help remind or educate others. hope things are looking up for everyone else.
