Go to Alaska Industrial Hardware in Anchorage and pick up a Tradesman 110 gallon L-tank and also a Flow right 15 GPM pump and you will be set. Figure you will spend about $600-$700. I bought one of these units like this set up for $400 and I have not seen another used one that good yet. If you don't want to spend the money I can give you a couple 55gal drums from my work and you can buy a $150 hand pump and pump it out of the drums as you drive down.
Juat a side note I came up from Montana a couple years ago in my 05 pulling about 14,000 lbs. I filled my 110 gallon L-tank in MT, then contined to fill up just the truck until I got to Dawon Creek, toped of the truck and with 110 gal in the tank I made it all the way to Wasilla with out having to fill up. The tank more than paid for itself.
Hope that helps. Shoot me a PM if you want some drums. :thumbsup
