First off I know nothing about trucks. I'm posting this asking this for both me and my husband. We're driving from Washington State to New Jersey this August. We're stopping in Oregon, Texas, New Orleans and then finally in New Jersey where we'll be for the next 3yrs. His truck gets pretty crappy gas mileage in my opinion. he has a 2001 1500 4x4 off road v8 with a shortbed (dunno if the bed makes a difference). We both want to maximize the amount of gas we'll get.
So I was wondering if there is anything we can do to the truck to get better gas mileage. He may also tow a small travel trailer. Don't know yet, I don't want to but he wants to. I know on cars there are some things like cold air intakes and stuff that you can change that will give you better gas mileage. Is it the same on a truck or different?
