My unit provides 30amps, so couldn't use anything else when this would be on.
Don't even think of of doing that. Some electrical fixtures are out of your control. What happens when your water heater and converter (battery charger) kick on at the same time? Or the air conditioner?
Would the family be happy if it were 100 degrees and they had to turn off the A/C before they took a shower or washed dishes? How often would they forget?
Be reasonable. Propane is not that expensive, around $12-14 at Costco for a 30 lb. cylinder that lasts all summer. And it's not fixed fee. They meter the fill and only charge for what you get, so filling every time you've camped a couple of weeks won't break the bank.
At the campground where our Cherokee 38P is sited, electricity is measured and it's much cheaper to use propane.
