Been towing my boat with my 98 expy 5.4L with the towing package. According to the stats, I should easily be able to tow this boat, with about 1500-2000 lbs of capacity to spare, but the truck labors and barely gets above 50 mph. My friend tows a larger boat with his Navigator with basically the same engine.
The previous owner put on larger tires (265/70 r16), so I think that may be affecting the performance. I'm considering swapping to a 4.1 ratio in the rear end to make up for the larger tires.
Has anyone out there done it? If so, how did it work? Cost?
