I'm going to be traveling in a 37' Fleetwood Discover between Alaska and Seattle. I'd like to think that I can find wide spots in the road in British Columbia, Alberta and NW Territories but I don't know what the rules are. Can anyone offer any guidance? Thanks, Craig Pollock

Southern BC is tight and hard to find spots. It gets easier, the further north you go. You'll be going through Yukon territory, not NWT, but there's lots of open spaces there, too. Alberta, again, is more open in the north. 

ETA: Definitely plan to stop at Liard Hot springs, either coming or going. Or both.

We found plenty of places to stay.  In British Columbia you're not allowed over 4 hours time in official rest areas.  However, there are many other turnouts or open areas to stay.  You'll see many others stopping at various places and you'll soon get the hang of what to look out for. There are some nice Provincial Parks and in the Yukon the Provincial Parks are awesome and most of them also supply wood for a campfire.

We didn't drive long days ; sometimes just moving 100 miles or so and we stopped at places we wanted to explore more thoroughly so we usually stayed in Provincial Parks.  Don't rush through Canada and the Yukon.  There are some gorgeous areas; some even prettier than Alaska.

We went up on the Alaskan Hwy and returned via the Cassier Hwy..... spent the summer.

Have a great trip.  It's a very easy one to do …… just long.

The typical routing is north from Dawson Creek to Whitehorse. Then you have decisions to make. Consider Skagway, Dawson Or Tok. You get to chose one going up. First trip was Dawson, TOW, Chicken, Tok, Valdez, Anchorage, Homer, Seward.  Denali, Fairbanks, Hyder. Second trip was Whitehorse, Skagway, Haines , Fairbanks, Denali, Homer on the Spit. Kenai Seward, Palmer, Fairbanks, Tok  Chicken, Eagle, Dawson, then down the Cashier to Hyder. First trip was three weeks. Second trip was three months in the north. Memorial Day weekend is really the start of the tourist season to  make your schedule interesting. You really need to see the Frantic Follies in Whitehorse. Visit the theater in Dawson for the Muppet boxes. Study the historical weather for insight into when to visit the different areas. Denali and the Kenai Peninsula in June. As the summer progresses the weather becomes more  wet. On the second trip we saw the Denali, Mt McKinley, completely open for four days.

Fred Meyer store in Soldotna allows three days in there RV parking with water and a dump station. 

Enjoy your trip.

I second Linda suggestion about Days End:   https://daysenddirectory.com/#/    

There are a lot of overnight or longer sites documented in Days End for the AK highway.  A number of them I updated or added during our 2016 trip. 

Also, a good campground/RV park/boondocking spots reference is Mike & Terri Church's 'Alaskan Camping' which includes Canada & the Yukon.  Well worth the purchase before the trip.

X2 on Church's Camping in Alaska and Canada. Milepost and Days End. In your budget for the trip this cost is a non entity.

Good trip
