Thanks very much for sooo much fast response....
Here's the link to the post from 2010 that i think may be a good instruction but I am not sure...

Anyway, what I have is a 1999 Rexhall Aerbus, XL3550BSL. Two AC units, and a Generac 5KW generator that the manufacturer (Rexhall) says would run the two AC units at the same time but the coach is 30 amps....so there are switches in the coach to select one or the other AC units. I see quite a few discussions on how a mod would allow for the two AC units to be run at the same time from the Generator....but I am just not experienced enough to know for sure what I am looking at with these mods....
So my question is after you look at the post from 2010 above...Pictures and nice instructions.....will this mod allow me to run the two AC's at the same time with off the generator?
