hi jerry and welcome to airforum'n
twink....i think he has 3 a/cs counting the dash unit....
my mo ho only had one roof air.....
seems that in the moho threads this has been discussed....you need more than 30 amps to have both roof ac on at the same time...
seems i recall some solutions are set up as 50 amp while other are 2 separate outlets...a 30 and a 20 just for the rear ac unit...and only the front is wired into genset?
read some of the old moho threads.....
or you will have to wait for the moho heads to jump it...they are all busy trying to figure out that hole in the dash!
cheers
