Welcome Sailor Bill.
There are a few comments re: all electric at this link:
It's about an Xplorer not a Gulfstream BT Cruiser though.
You'd narrow down the list of potential buyers on resale I'd think. I'll create a poll asking "Would you purchase an "All Appliances Electric RV?". It'll be interesting to see the results. Resale only matters if you want to ever sell it.
My fridge and water heater are gas or electric.
My furnace, stove and oven are propane only.
