Newbie with a few ?

[tonto13]

I am new and had a few questions. I am going to look at a 97 F-350 4x4 quad cab longbed. It has a 4" lift w/ 35" tires. Said he had a tuner for it that he took off when gas got expensive. It has an auxillary tank in the bed. 128,000 miles. Motor is stock. What are some of the things I should look for? Questions to ask? I have always had chevy gas vehicles so I do not know alot about these and any tips would be very appreciated. I will be using it to pull a 22 ft. bumper pull enclosed trailer mainly. I have always liked the looks of these trucks and always wanted a diesel, hope this truck turns out to be a good one. He is asking $7000, fair price? Sorry for so many questions on a first post. Just going to look tommorrow and really just kinda excited. Just want to make sure I really cover all my bases the best I can. I am tired of pulling the trailer with the gas motor and feeling everybit of the trailer behind me on every hill. Thanks for any advice!

why would you take the chip off when gas got ex. seeings how it improves fuel econ.

He said with it on he was only getting about 10mi. to the gallon. He said it was a tuner.Said he could feel the difference just worse mpg. Said it had different settings tow, economy and a dew others. Does this sound correct?

[justafarmtruck]

should be getting better mpg. with it on

I know he put a 4" lift w/ 315/75 tires and did not change the gears or recalibate the speedo. That was my next question, How do you recalibrate the speedo? I have an idea that is a contributing factor to the trans going out. Said he has rebuild with papers. I know if it does not read right then will not shift right and buils up heat.

I just talked to him again and said it was an EDGE tuner/programmer. Which ever it is. Is this one any good? Does anyone have anymore tips?! I am going to look at it tommorrow at 1 p.m. and taking my brother with me, seeing as he has a 97 also.
