> vehicles are taxed based on weight- a 1 ton pickup will cost more each year to register than a compact car or motorcycle

An F-350 is 3.7 tons.

Two problems with this 1) It's unlikely to be proportional to road damage - if a 1 ton vehicle that costs $100 to register, a 2 ton vehicle should cost $1600, and a 4 ton vehicle should cost $25k. 2) It doesn't take into account mileage. Own a heavy truck that you use on your own land, and do about 1,000 miles a year on the road, and you pay the same as someone that has the same truck but does 50,000 miles a year commuting.

The odometer idea elsewhere in the thread probably works well for the U.S, just have a website to post your mileage when you drive into mexico/canada, and again on the way back, with spotchecks at the border. People who do significant mileage on their own land will be annoyed, but they currently pay gas tax on that mileage
