AC voltage and line loss
Hey guys, I have a 96 Bounder 34j with two brand new Coleman 13,500BTU AC units.. the weather is extremely hot right now and everyone is running their AC’s... even with my Hughes Autoformer I’m runnin...

Hi,
No, you can not just go to a larger breaker. That is one reason I have the twin auxiliary shore power cords (each is 20 amps). Because I added male and female plugs I can switch back to OEM configuration in under a minute.
Originally, I had a large battery bank (875 amp-hours) and a 2500 watt MSW inverter. I was often in locations where there was only a 15 amp shore supply (sometimes of dubious voltage, such as 97). I "broke out" the converter (which was a plug in PD 35 amp) so only it would be plugged into the shore power. The rest of the RV ran from the inverter. As a side benefit, the risk of popping the shore power breaker was minimal, as the converter topped out at about 750 watts.
This is referred to as "double conversion". It is wasteful, electrically speaking, but it did allow me to have full functionality of my RV. I did not feel comfortable running the roof air on an MSW inverter--but I did test my ability to do so. (it worked).
My RV can behave as if it is on shore power without generator use as I trundle down the road.
Adding the two auxiliary cords cost less than $100.00 for materials. I did have an electrician do the work as I needed to "snake" two wires from the rear of the RV to the front, so the inverter could be within two feet of the battery bank.

Thanks for the info, are you saying I can put a better breaker on the main that can handle the continuous load? I have 50 amp power available and the dogbone to use it, but obviously I’m not a 50 amp rig... I would gladly pay an electrician to make me 50amp but I can’t get a clear answer on whether my Intellitec will still function. Believe it or not i like the stupid thing (I would ditch it faster than I could click check out if there was a newer digital replacement!)
