Towing and gas mileage

[Craigerz]

Don't know where to post this but this is where I usually post so....

Do you think there is any difference in MPG in say carrying 500 lbs of cargo in the back vs. carrying 500 lbs of cargo on a trailer?

Yes probably a little. With the trailer you might have another couple hundred lbs trailer weight (or more), drag from trailer tires and worse aerodynamics. I'd still use the trailer if you have too much rear end sag loaded, guessing the loss is only a MPG or two.
