Just did this last spring, sort of, I'm still here....
First, dont waste your time coming up this year to ride.
I'm farking pisssssed off right now. Only full winter in AK and the ONLY riding other than some hardpack was Nov and Dec and even then, the mtns never got a base. Just a couple bottomless pow, land mine rides.
Cheapest way to get them up is to drive them up. I priced it all out for 3 snowmachines and 1 wheeler.
Depends how long you'll be here though. But you need wheels and a trailer anyway, so if you shipped the sleds then presumably you'd fly up and rent a truck and trailer? Ship the whole thing?
I drove up last year, loaded down with sleds and wheeler. Needed to bring the trailer and truck anyway though. It's an awesome drive and good experience.
Coming back to the L48 later this year, I got a deal w/ Carlile to haul them back. I crate them (in crates from a dealer) and they will store them and ship to Tacoma for about $250 per machine. However costs to ship North TO AK are 2-3x as much shipping south.
Being that its a shatty snow year and already March. If you do actually come up, the cheapest thing to do would be to buy a sled, ride the piss out of it and sell it before you leave, provided everything else is worked out for your trip. Bet you could ride for a week or 2 for $1000 easy that way. SLeds dont cost much if any more here than in the L48.
If you do decide to drive, see how much you can haul up for L48 folks for some gas $. Then buy the best deal you can find for a nice trailer, any kind, sled trailer, flatbed, cargo trailer, whatever, and sell it before you leave and haul your sled back in your pickup. Trailers of any kind are effing expensive here. Pretty much guarantee to double your money or more.
But, for real, unless it gets ALOT better, I'd rather be at my place in Gypsum, CO this year hands down for snow.
