Well I went over the 300 mile mark. The books break in period is done and I have a Pontoon boat in need of some TLC before the Salmon run gets here. Boat and trailer together are about 3000bs. Max handled it like a champ. There was a little surging but I think that had more to do with the wind then anything else. This is my first time with tow mirrors I don't think I'll ever have a truck without them again.
Now the bad news, this means I've put over 200 miles on Max in the first week.
I don't anticipate doing nearly that much long term. It'll slow down once I stop finding random excuses to jump in the truck.
Speaking of which we are a little low on milk...
