OK people. I live in Florida and I'm thinking of taking a job in Anchorage Alaska. I will get a sign on bonus which is mainly meant for cost of shipping all my property and vehicles up there. I have done a large amount of research and everyone says to take a week or two and drive. They say it is a once in a life time experience. It will cost $5,000 to ship my truck to Anchorage, so why not spend that amount and have a blast getting there instead. To this day I can remember as a kid my family traveling 3 months from east coast to west coast and what a blast. I currently have a 2001 1500HD RWD with 4:10 rear end. We all know the great gas millage I get. The trip if driving straight with out sight seeing detours is 4773 Miles. There are some portions of the trip in the Yukon that will not have adequate fuel stops. Here lies my problem. Fuel capacity…. Also, I will also be towing a 6 x 12 dual axel trailer loaded with everything I can toss in it and my bed with topper will also be stuffed. I want to one of the following: 1. Larger bolt up fuel tank (If possible) 2. Secondary tank system with switch and selector (If possible) 3. In the bed transfer tank So far this is all I could find and I really leaning toward this 109 Gallon set-up. http://www.transferflow.com/refueling_tanks.html I wanted to keep the bed looking stock, but I have not been able to find any sites or info on making my truck a dual tank monster. But if I do get the 109 Gallon bed tank at least I can remove it and store it for future trips when needed. I'm also going to buy a front bumperguard/winch set-up going HD due to moose accidents and would rather save front end as much as possible. And wanting to replace my side mirrors with heated mirrors for the winters. http://www.stylintrucks.com/parts.aspx?category%7ccategory_root%7c-25=Exterior&category%7ccat_-25%7c147=Bumpers&canned_results_trigger=&partid=494664 http://autopartscorp.com/product.php?productid=113874 INFO INFO INFO...
