I have a 2000 Chevy Silverado 1500 with a 5.3L V8 and 4 wheel drive. I haul two commercial mowers and a 6.5x12 open utility trailer. I was considering buying a new truck in the fall... a 2011 F250 is what I have my mind set on. My question is: Will towing my trailer with a heavier duty truck save on gas because it pulls it much easier than my 1500 Silverado? If not, what other options do you recommend. I have no clue what my MPG is on my current truck, or what it will be for the F250. I would figure my mowers together to weigh around 1500 Lbs and I don't know what the trailer weight is.
