Drive a fully loaded '04 Sprinter van (approx 8000 lbs.) daily. Get 20-22 mpg regularly (2.7l Mercedes turbo diesel).
When towing my '06 19CCD, I am fully loaded with motorcycle in the van, tools, toys, bicycles, more toys, a few clothes......you get the picture!
Anyway, my CGVW is 13,550 lbs and I last scaled the whole ball of wax at 12,220lbs total gross. I get 14-17 while towing at 70-75 mph. This trip will be markedly slower and mostly off the interstates, so I expect the mileage tro increase 10-15%. We'll see..................
The journey starts in mid-May
