Before replacing components, check for obstructions in the fan area. It is not uncommon for wasps to build nests that keep the fan from turning which results in the symptoms you describe.
When I opened up the AC, I checked everything and it all looked pretty good. This spring when I washed the trailer I took the cap off and cleaned it all up, including using AC foam on the AC coil. Got a few mud dobber nests out of it, but it's good now. The fan side of the capacitor is testing bad, and the new one came in the other day. I just have to get back down there and install it. Thanks for the suggestion!
