What are the trucks for...
We lived in Calgary Alberta for a while and my wife worked in the office of a company called Canadian Foremost. They made vehicles like these for travel over the tundra for oil exploration, drilling and site restocking. The large terra tires allow the vehicles to "float" over the soft ground in all types of weather.
They are in use in the "northlands" all over the world.
My wife just reminded me that they also shipped vehicles to desert areas in the middle east for use on desert sands.
I like to read travel logs like this to Alaska because we too along with 11 other RV's traveled from Phoenix to the arctic circle, around Alaska and British Colunbia for 100 days in 2004. We traveled about the same 10,000 miles. We did it early in the season before the tourists and large travel clubs. We wee back home by mid July.
Had a great time and it is on my bucket list to do again.
If it is your dream to do this, don't put it off too long. Life is for the living........
