No, I'm afraid they don't let you do that. You can rent a cabin or sleep out on the fantail deck. They provide lounge chairs and there are overhead heaters on the ceiling. But this area is open to the outside at the rear. So, just top and 3 side protection. I have seen people bring sleeping bags or heavy blankets to sleep under. We brought our dog on the last trip from Haines to Juneau. Takes about 5 hours (& $1,000 round trip). She stayed in the trailer the entire time. Just made sure she had plenty of water and access to the bed to sleep on. Obviously, not all dogs can handle being alone this long. As for driving the ALCAN it is about 1,600 miles from Mile 0 in Dawson Creek, BC to Anchorage, AK. As for fuel - Average price for gas in Canada was about $5.19 / gallon and $4.67 in Alaska. This does very widely - the farther north in Canada you get the more expensive it is. As far as pitfalls. The ALCAN is actually pretty tame these days. The worst section is from Destruction Bay, YT to the US border station (150 miles). Especially the 20 miles between the US & Canadian border stations. Worst bit of road we've ever driven. The best way to approach this is to drive SLOWLY. Pay attention to changes in road surface color, look for orange cones / signs and skid marks (when trailers hit the back side of a frost heave the tires skip/Skid). The other major thing is the distance between gas stops. Know your range and plan accordingly. We carry 10 gallons of extra gas just in case our mileage varies a bit. Otherwise the scenery is beautiful and boondock spots are plentiful.
