    Real world 13-14 city 17-18 hiway it all depends how you drive. I can get low 14's pulling my 41ft toyhauler and high 22's running empty. Both of those numbers are driving like an old man and hand calculated. If someone doesn't believe I'll take you for a ride.

    That's also your LBZ's, the LLY will do a little better IMHO. I havent calced mine much, but my last LLY would do 14-15 city and 21-22 highway empty, lifted and on 35's. I calced my 05 once on the highway for a 500 mile round trip was 23.3 empty under 2k the whole time, that's bone stock on 265's. Since, I've eliminated the cat and put on a cold air intake. Probably picked up .5-1.

    I can get 22-24mpg empty on the highway with cruise set on 68 mph, 15-17 in town, or 10 mpg on stage 7/speed loader in town showing up sport compacts:D. Pulling landscape trailer 8000 lbs 26ft with mowers 100 mile route everyday about 13-14 mpg. dic says 135872 miles and 9675 gal of fuel pulls 5-6 days a week and never sits still more that 10 hours.
