Two thoughts.. You said you removed the outer cover, Did you also remove the cover over the condenser coils? This is where it really gets gunked up, in the "Backside" (Fan side) of the condenser coils.
Page 2. HOW HOT WAS IT (outside the RV that is) the hotter the more the compressor runs.
Finally a quick check you can run that does not even require a ladder!!
Using a clamp on AC ammeter, Carefully CAUTION DANGEROUS VOLTAGES EXIST open the breaker panel and identify the wire that runs to the air conditioner you are worried about,, Fit meter over wire in the manner explained in the meter owner's manual and measure current draw. Compare to the A/C's specification lable..
Example. mine is 13.5 amps.. So if it's much less than 10, or more than 15 I have a problem. (It hit 21, the condenser was clogged)
Let it run for a while if it's normal.. (NOTE Starting (first second) may be higher) took mine a few mintues to hit 21.
On my particular rig, it was a 30-amp setup. I optioned in the 50-amp service when I optioned in the second A/C. To the best of my knowledge, not much is hanging off that second leg besides the second A/C as I never see more than an amp or two draw when reading the progressive industries meter which cycles 24/7. When the A/C is running, it jumps to about 19 amps, I think. I'd have to look again to remember. When the A/C compressor is cycled off and just the A/C blower is running, I see 5 amps of draw. Voltage on each leg was reading between 116v and 118v the whole weekend.
