Texas Diesel
As Larv say's fuel is not a problem. I have a transfer tank and pack 100 gal total. We travel with friends with a dodge with stock tank and they will fill up every 200/250 miles. Plenty of good stops for fuel. Don't worry about the Bears at that time of the year they are still in hibernation, also you wont be cooking any fresh fish along the way unless you bought it in a store. All the lakes and most rivers will still be frozen over. When you get to Dawson creek it will be right at 1640 miles to Anchorage. When we travel from Yuma to Anch it is 3,806 miles. We can do that in 6 1/2 days. The Canadian border at Sweet water start of I-15 to Anch is 4 long day's. Lethridge 60 miles north of the border is a good over night place. Also temperatures going north will mostly be freezing at night for sure and good chance during the day, so you might not be able to use your water system in the camper. If you really want to carry a weapon an 18. 5 " barrel shot gun with 3" mag OO buck is a good thing to carry. Go on line to the Canadian firearms website first and down load the form for guns "909" and fill it all out. Only one copy not 3 as they will run it through the copy machine. The permit is good for 60 days but is renewable up to one year at no extra charge. Also bring at least 75 canadian dollars with you. For incidentals and for the $25 canadian that the gun permit will cost you. During the day at the border stop with a larger customs crew you can use a credit card but after hours we found they want correct money in canadian $$. For all your purchases Food, Fuel, Motel, use your credit card and let the credit card do the canadian exchange. Best deal for you in the long run. The credit card company will charge you a couple of bucks for the service. North to Alaska next Wednesday and counting down. One more thing as you cross the border at Sweetwater a few miles into canada there is a little town that is "Milk" something. On the east side of the road going through town they have a you do it truck wash. The car bay is big enough for a truck and cabover camper and it has the most powerful pressure washer I have ever seen. I did mine and it was the best $12 canadian I ever spent.
