If you put a pencil to it, if you have to run your generator all night for AC Wal Mart might not be such a bargin if you compare it to a $30 per night RV park! If the genny uses .8 gal/hr for 10 hours that's 8 gallons X $4.02 per gallon your total cost is $32.16 not counting the cost per hour of fuel filters, oil fitler & oil.
Just sayin !!!!
