Re: towing with a chevy silverado v6
I had a 2000 Silverado with the 4.3l V6 5-speed manual transmission and the only problem I ever had with it was typical of most trucks ? a very light rear end. I think you will find yourself spinning your wheels quite a bit on wet, inclined boat ramps.
I pulled 1-2 ton loads with it on several occasions without a problem. The larger loads where mostly around town, but I have also hauled large loads up the hill from Phoenix to Flagstaff. Be sure to leave yourself plenty of stopping space, though.
The gas mileage of this truck is one of its advantages. Completely stock I got an average of 20 mpg, mixed mileage (freeway/in-town). To further increase this, I put on an Air Raid cold air intake and throttle body spacer to up my average to 24 mpg ? as long as I was easy on the accelerator. The throttle body spacer adds more to low end torque than to mileage, but still nice to have.
You might want to see if you can figure out a test run somehow. Maybe an unused diesel truck ramp and a couple buckets of water? Back it down a dry ramp, wet the pavement in front of the rear tires and see how you do. You might even want to try pulling it up on dry pavement first.
