I have a 30' class "C" with a Coleman 13.5. Boondock often in summer and winter. Tried using my Honda 2000i with a hard start kit did not work. Installed the Easy Start, board & following the start-restart procedure I was amazed that Lil Red (the Honda) handled the load very well. In ECO mode when the A/C came on, first the fan started causing the gen to rev up from idle to full power 1 to 2 seconds later, the compressor would start and run. Within 2 seconds "Lil Red" would reduce revs from full power to about 70% of max rpm. Thus saving gas and noise. I usually put the fridge & water heater in gas mode. Sometimes I kick off the converter to further save load.
The on-board Onan is noisy and needs .5 to .75 gallons of gas per hour (Appox 12 to 14 Gal per day). Lil Red only uses 2.5 to 3 gallons per 24 hour period of continuous operation in the Florida heat. Usually I will run the Honda for 48 (ish) hours straight then change the oil for the next 48 hours. (Takes about 15 oz of Mobile 1, 30wt)
All that was to say the Micro Aire was a great addition to my RV and I will do it again on my next MH.
Highly Recommend. If you are a real DIY purchase the board and build a box to install.
