4000 mile run, plus or minus 150 miles pretty much all of your 70 hours in good weather. I would not run this type of trucking for anything less than 35000 dollars which will take into account certain expenses such as Alaska tags and not getting anything back to the States among other potential problems.
I think Alaska Air has daily flight out of D/FW. Go mid-week and you can get some good deals on the rate. Alaska Air has good snacks.
Used to be in British Columbia you had get a special permit and something about you had to park before pulling on scale to get the permit. If you pulled on a scale it was a ticket for not having the permit. I think you have to get Alaska permit it like $300
