Thanks DD. The only day we needed gas was the first one. Masquite to Bar10 to Toro Weap. Joel made the arrangements for it and we got 87 at $7/gallon. :eek1 My 990 got 2.8 gallons. Less then DR650. BTW, my mpg thorough out the trip was way over 40. I hardly get over 40mpg but on this trip I got 47, 49 and 49 mpg per tank. I keep track of it with an app. Other than that I thing 120 miles per tank would be enough, unless you get lost. Joel will help you out on this one, on both.
