Soft start capacitors

Adding a "hard" start capacitor that reduces the starting current would be a good thing for starting under low voltage conditions and where wire runs to a pedestal are long because the motor windings wouldn't get stressed as much at startup and could potentially reduce the chances of premature failure of an AC unit. How many RV-ers monitor voltage or know what good or bad voltage levels are tho?

I think all AC units should have them but just think of the increased purchase cost of a new RV... :R And just guessing, I would expect that the AC unit manufacturers would rather sell you a replacement AC unit than a capacitor.
