While I was in the dealer the other day a customer with a 29.3 had installed a second A/C (the dealer said he could with all the installed wiring and 4000 gen). What he was trying to convey to the service person was when he had the first A/C on everything worked find (using the gen). When he try to start the second A/C the generator would surge to the point of almost stalling out. Long story, is the installed a regular 15,000 BTU A/C unit. With both trying to run off of the generator it can not produce the AMPs to get the 2nd A/C up to speed and maintain the required power to both. A tech was called in to see what could be done. He said there are A/C units out there that have really low draw but are only around 10,000 BTU's..... So that might be a way to go. I haven't researched it yet to see if that indeed true. I do know for the Thor models like ours, there is ducting and wiring set up already. You have to remove the rear fan/vent and everything is there.
