Inverter/Battery/load combination
All, I just took delivery of a new Cardinal 5er. Came with residential Frigidaire Refrigerator, Label says 8.5amp draw The coach also was wired with a Xantrex 2000W ProWatt SW dedicated to power...

What size wires are connecting the battery to the inverter? 18" is good but they still have to be fairly thick. It's probably drawing on the order of 90amps-12v.
I would test at a site. Disconnect the shore power and see if the fridge kicks on if you turn the thermostat down. 10 degrees loss in an hour could imply it wasn't running at all and just functioning as a built in cooler. 8.5amps would be about 1000watts but typically getting a compressor to kick over takes 2-3 times the amps, so 2000watts would be marginal to get it started.
1GA. My plan is to try that today at our current campsite today. Xantrex manual indicates that the inverter is good to 3000 watts surge, 1800 watts continous.
