Need advice on choosing another Tow Vehicle?

I just got back from visiting a dear friend that is on the border of the promise land (last days). His son is an expert Ford mechanic. I had a long talk with his son and he feels my truck would be much better off with the 3.42 gears in the rear end. He suggested picking up a rear end a salvage yard and just swapping it out and keeping my current one for the future if I stop pulling.

I think I will skip this and keep my existing gear for the time being, but he did talk about getting an aftermarket chip for RV towing. Anybody have any experience with aftermarket chips?

After market chips open up a whole lot of possibilies for mods.

Your can recalibrate the tire size if you changed tire size, reprogram the ECM to change shift points and give a firmer shift, change engine mapping to produce more power from things like a high flow airfilter and low restriction exhaust.

You can get two different types of tuners, on that you plug into the ODBII port and reprogram off the chips screen or there are tuners that have dash or A-pillar mounted display screen. The second type of tuner usually allow you to change power settings on the fly.

I have used both types, a Superchips plug in and reprogram the ECM on my Ford gas. I have the display on my Ram Cummins. The dash mounted screen allows you to monitor several functions at once. I when with the screen version for several reasons, the ability to monitor trans temp, boost and exhaust temp were my priority. As an added bonus it has a built in turbo cool down timer. Allows me to stop, shut the truck off and walk away, the truck runs until the EGT gets to 380F then shuts down.

To get a decent tuner with a display your looking at several hundred to a thousand dollars.
