ah, there's the difference. around here everything's 4wheel drive and everyone runs 31x10.5 tires. front air dams generally don't survive the first winter.



fyi, you're getting better mileage in your 5.4liter suburban than I'm getting in my 3liter 4runner. well done, lightfoot!



so, according to your numbers, towing your f25c cuts your fuel mileage by 40%??? it may be worth my trouble to head up to canada and get a diesel land cruiser after all!



thanks again.
