Went camping last weekend and plugged into 30 amp shore power at the camp site. Started both Duo Therm roof AC units and they ran well for a couple of hours. Front AC unit then then continued to run but did not cool air -- ambient temp at best from the discharge into the coach. Shut unit off and managed to get through the balance of the weekend with only the rear AC unit operating.
I believe both AC units are 13,500 BTU units-older models. Looking for confirmation that I can only run a single AC unit when using 30 A shore power. If that is the case, why were both units able to run for a significant period of time and then one unit fail to produce cold air? The AC unit that "failed" last weekend today runs well and produces cold air. Is it true that the only way I can run both AC units simultaneously is when my 6000W Onan generator is operating or if I'm plugged into 50 A shore power?
This may be a no brainer question for experienced GMC owners but this is the first summer I have used "The Never Ending Story" since I bought it last fall.
