Looking for a generator

[RMcNeal]

Thanks. That's helpful. My Samsung frig is rated at 5 amps. It's the inverter type.
I have run the frig, converter and 1 AC on 20 amp home receptacle. Cord didn't get warm. Everything ran fine overnight. I was trying to get the coach nice and cool before we left in an effort to shorten the time to cool down at our first stop. Haven't installed the Easy Starts yet.
I was hoping to get a generator that would run these 3 items to keep the coach cool while travelling. My problem is, I can't find a generator that can do that and fit inside the bed cover of my truck (when not in use). I only have 19" height clearance under the Retrax Pro cover. Everything capable is at least 20".
I had considered turning of the converter and running the frig off the batteries while travelling. I have 2-GC2 golf cart batteries with 215 AH that should be fine for 5 hours or less of travel.
