OK, its been a while but I found the receipts for the gas purchases the other day and I just wanted to post that info in case someone is thinking about doing a trip like this. Now prices have fallen a bit, so I imagine a similar trip would be less expensive but this gives you a good idea of what we spent.
Date Gallons $/Gal. Total
5/31 - 31 gal - $4.06 - $125
6/2 - 28 gal - $4.06 - $107
6/5 - 33 gal - $3.80 - $125
6/6 - 32 gal - $3.88 - $125
6/12 - 23 gal - $4.30 - $100
6/14 - 50 gal - $4.04 - $200
6/15 - 32 gal - $3.98 - $125
6/16 - 66 gal - $3.83 - $251
6/19 - 35 gal - $4.90 - $170
6/24 - 34 gal - $4.40 - $150
6/24 - 30 gal - $4.10 - $125
6/25 - 48 gal - $3.62 - $173 (topping off for RV return)
Total spent on gas: $1,776. That is a little more than I had budgeted for. We favored filling up more frequently instead of topping it off. I would say we filled the tank between half and three-quarters full. Otherwise you are just carrying more weight and remember, gas weighs about 6 lbs. a gallon. That extra 20 gallons is like adding another person on board.
