The run caps for the indoor & outdoor blower motors are mounted inside near the motors. I'm looking at the RVP 6535 Service Manual sketches and schematics. It appears that the two blower motors don't have start caps. Only the two compressor motors haves both start & run caps which are behind the metal access panel.
I've been using the 50A Hughes Autoformer for the past 14 yrs on this coach and never had a capacitor failure in my basement unit and that's with 7 yrs fulltiming and a lot of a/c time. Low voltage is a real killer on the start circuits and induction motors. I don't have any first hand experience with cap problems.
Your problem John, could be the outdoor blower motor bearings are so worn that the rotor is dragging against the stator. That is a typical wear problem with my VW engine starter motor in my dune buggy. I would open the access panel first to see if you can find a visual problem there. Most likely you'll have to drop the unit to replace the run cap and pillow bearings and/or outdoor motor.
