The Best Half Ton Towing Truck - Ike Gauntlet

I've owned two different 6.2's. One with the 6 speed and one with the 8 speed. I now have a 17' 5.3 6 speed. I was thinking that there would be a huge difference in acceleration when towing between the two. I can honestly say there really isn't that much difference. The 8 speed had a 3.42 rear gear and the 5.3 has 3.73's. I'm sure that helps the 5.3. How much is anybody's guess. The 6.2's are awesome and get better mileage than the 5.3 but I won't be getting another at this point. It isn't worth the $2500 upgrade from the 5.3 IMO. As far as GM sending them to a towing test, the 3.5Ecoboost isn't the standard engine for the F-150 so I don't see what the fuss is about.
