I just got a Black Max 3600 Watt generator (on sale at Sam's Club for $299) and it will power the 15k AC, the microwave, the fridge, and the TV all at the same time with power to spare (according to the EMS reading). It has the 3 prong 30 Amp receptacle for direct hookup of the rig power cord. It only weighs 110 pounds and is easier to get in and out of the truck than the 7000 watt Black Max gen that I have. I will convert it to Tri-fuel at a later date as propane is more efficient, cooler, and quieter than reg gas. It also has a floating ground so I needed to use the grounding plug that Progressive sells.
