Nice job. Great performance upgrade for the cost.
It seems that the electrification of RVs continues to progress steadily, with equipment manufacturers addressing RV manufacturers' needs. Xantrex just introduced to OEMs at trade show a new 1200-watt inverter for refrigerators, microwaves, coffee makers, etc.
Also of interest is their mention of development into lithium battery system to run air conditioner without generator or shore power. We can only imagine the battery bank's size and cost.
Anyway, hard to have too much battery capacity.
