CaptRonB - Like you, I had the same idea which is how I ended up here. The advice you (and me) got was great.
Hopefully, it doesn't sound like I'm beating a dead horse, but I have a question about the higher consumption rate for propane, I see the Beem 2700 watt unit claims it consumes .38 gph which sounds pretty good. I'm also very new to RVing and sometimes believe their advertised specs. Here it is:

Also, it claims 31.7 amps. So, it sounds like a 2,700 watt propane generator with specs exceeding my 30 amp RV's needs and weighs just 68 pounds is available for less than $1,300 Is it really too good to be true? Oh yes, Northern Tool is selling it too.
Thanks
