Update:
*Using a commercial 30amp 3way light switch...I have discovered what I had hoped for. My 2000 watt Digital inverter will handle the "running load" of the 13.5k rooftop ac.
*I will have to use it to merely cool the MH periodically when not plugged with shore power and this means setting the ac at the coldest setting until I am happy with the temp, then shut everything down. (not allowing the thermostat to cycle the compressor, just going for full cooling and calling it good enough for a period of time)
**I removed the burned out thermal fuse from my "Kill-A-Watt" and quick repaired it to see if I could get a better idea of the start energy the 13.5k ac unit requires.(dangerous repair...bypassed the fuse..):S
-Many repeated attempts give me an average of 27 amps(3240 watts) when the ac is first turned on, with an immediate rapid decrease to the approximate average I already calculated while running on high cool(13.45 amps/1580 watts) . The watts reading on the meter is too slow to give me a reading for start-up, so I used the amps selection on the meter. This is accurate as I can calculate/test with what I have and to me, it seems proper.
(the 50 something amps proffessor95 mentioned as "typical" had me worried)
I am happy with all the assistance and information I have received from this thread and its members. I know for some, what I am doing is "against the grain" according to their opinions, but my budget and timing of events is what it is for my situation.
Over-all, I am happy with my results so far and what I have is functional plus decades above the technology it was when it was built in 1977. Sure it is not the "most convienant", but it very much "works for me".

I am undecided on the decision between pure sine wave and modified sine wave for converters, it'll come down to the $$ when I purchase.
I have decided to stick with the 30 amp commercial 3way switch, it is simple, cheap, and easily replaced for my situation.
