I'd also strongly consider electric fan conversion

How much power increase will the header, cats , intake and programmer make? How much would it cost?
I tow 2x a year about 200 miles each way currently, the most I would tow would be 6 or 7 times a year if my h2 could pull it up the steep grades.

What is an electric fan conversion?
