Driving our homebuilt rig to Alaska....questions

I think the very first thing on the list for an Alaska trip is tires. Having tires in good condition and having the appropriate spares for your vehicles.

I had a heck of a time finding a 19.5 tire in Florida. Another time 60 miles east of Kansas City--wasn't so hard, but had to wait 2 hours for Wing Foot to bring some. That isn't going to happen along the Alaska Highway.

I think you will find hauling the boat up and back to be a HUGE Pita. I can assure you your trip will be much easier without it.
