Pulled boats for many years, now have a Rockwood Minilite 2014s. Pulled by Ford F150 Lariat. Gas mileage went from 16 mpg to 8mpg. Just want to see if this is about the average drop in mpg. Don't see ...
Limiting the top gear(s) when towing can also help. My 5.3 Liter Sierra gets better mileage towing in 4th gear then in 5th or 6th gear. The transmission temperature also stays lower and I can easily climb hills or accelerate. When I'm coasting down the freeway, I let it use 5th gear.
