The dash A/C (Quantum KM24 Sprinter) does a much better job of cooling the motorhome on the than the 15000btu coleman. Does anyone have a idea of the tradeoff in fuel cost of using the diesel engine to cool and recharge the house batteries vs propane gen. My log shows we paid as much as a dollar more/gal for propane out west. Just trying to see if I'm missing an angle. Thoughts, opinions?
