Ok - Thanks for the feedback - The Excursion has had the following modifications done - Engine - V10 (Banks Power Pack= Headers, Transcommand, Air Intake, Ottomind "Performance Chip) - Add-a-leaf / Firestone Airbags with onboard compressor / 1 5/8" Sway Bar - 4" Lift. I carry 3 quads (2004 Honda 400EX, 2001 Honda 400EX / 2000 Banshee 350. No Water or fuel until we get close to our destination. Inside of the vehicle - (3 people - 2 adults and 1 child). I don't think I've ever gone over the 11,000lbs or 10,500 - the quads weigh around 375 ea.
I've towed with this WW 15 times - with the total mileage pulled behind my Excursion to be 5500 miles -
