4x4 necessary?

Is that Hitchcrafters in NC that did that work? Looks good but it looks like those are the 22-24" fenders. The 19.5" sized ones would fit better.

Do you have a 7-way plug up near the 5th wheel or do you just run it to the back one?

 

Not too worried about the fenders, this truck will be replaced within a year. Not throwing anymore money at it. Didn't even notice they were too big till you mentioned it.
Yea the 7 way plug is up by the spare/5th wheel. No plug on the back.

 

I'd skip the 4wd and save the money, weight and MPG penalty. Mine is 2wd/DRW and that is what I wanted.
