According to Dometic, amp rating on a 13500 btu unit is 13.4 amps. Locked rotor amps are 63. They don't list the name plate voltage. The do want #12 wire for runs under 24 feet. More than that and they suggest checking the national electric code.

If we assume 115 volts then wattage is 1541. I know I've seen as low slightly under 1200 and as high as 1900. At 1900 and 106 volts that's over 17 amps flowing through the motor. I can't imagine this is good for it, as a 10% tolerance would be about 14.75 amps.
I don't doubt your figures, Don, but I think the AC motor may be more rugged than you suggest . . .
I just base that on the over 10-year-old residential fridge in my park model. The campground voltage can sag to 102V each summer, and there has been NO autoformer hooked up to that park model.
The fridge is still working just fine.
I don't suggest that low voltages are a good thing (since I use an autoformer), but I think many of the motors RVers use are pretty forgiving.
