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 wire gauge was recommended from batteries to inverter in the inverter installation manual for your length wire run?
1 Gauge is very likely too small.
And pretty easy to check:
Check voltage drop across the wires-- when someone starts the refrigerator, with a digital voltmeter check voltage between house battery positive and negative lugs.
Check again at the inverter positive and negative lugs. Any delta between the two means resistance in the cabling. 2% drop is commonly recommended for primary circuits.
While large gauge wire is not inexpensive, it is sure the least expensive "fix".
