Advice on taking an Amerilite 21MB to Alaska

I went to Alaska this past May & June, with my Coachman 192 RBS, TV was a 2003 Toyota Tundra. My TT weighted 4300 lbs. when I had to stop in Alberta for a watercraft inspection on my kayak. At road construction areas, I would pull over & let traffic go by, then proceed at a safe speed. A 18 wheeler is a small truck up there, Canada has 26 wheelers. I found the biggest bumps to be were the asphalt ended & the gravel road started, some of these were very abrupt. The frost heaves in the asphalt were fairly well marked. I entered Canada at Abbotfords, BC. & went up Hwy. 1 & the Cassar Hwy. This road was in very good shape. Stop & get gas every time you get down to 1/2 a tank & carry a couple of 5 gal gas tanks. We really didn't need bug juice (used REI Jungle Juice)until we got to Fairbanks in early June. Also needed air conditioning as it was unseasonably warm (±90°). We left Fairbanks on June 11, there was a steady stream of traffic going north as we were going south. Some of the worst roads we encountered were between Ft. St. John & Edmonton, a lot of oil rigs beating up the roads & bring mud on to the hiway from the side roads. Be sure to get a copy of the book "Milepost" available at Amazon. This book is invaluable. That time of year we only needed a light polar fleece in the morning. Also carried a rain jacket. Do it, you will never regret it.
