Things are always changing, so it's nice to have updates.  Last spring when we came up I figured diesel would be cheaper at the Hub in Glennallen, but it was 50 cents higher than the last place I filled up in Cananda!  So I just got enough to make it to Anchorage and filled up there.
I asked why the fuel prices were lower in Norhtern Canada and was told it was because they were barging fuel into someplace (Haines ?) and trucking it over which was a lot less transportation cost than bringing it down from Alaska or up from lower Canada.  It was an Alaskan trucking company, Big State Logistics, doing the trucking.  Maybe Joe, the owner, had set up the barging operation also.
If you wait until later in the evening, you can get a 40' MH into the Fred Meyers in Muldoon for fuel.  If you have a rewards card at Fred's, you get 10 cents off per gallon for each $100 spent, but you only get 35 gallons.  After that it's 3 cents off per gallon for as much as you want.  Come in on the entrance on Lake Otis which is the North side.  So go buy your groceries and then fill up.
And in Muldoon, just as you come off of the highway, is the City's little camper park.  Dumping will cost $10 but we use it because there's lot's of room to turn a 40' MH around in there to dump.  If youi're after hours, you can leave the $10 at the office.  I haven't tried going in there with the toad on, but I don't think you can do it.  Several of the gas stations have free dumping, but it's easier to pay the $10 than get into several of the free places on the east side of town.
