| I have a 2002 Tahoe with 263k miles. I venture to say that well over 100,00 miles have been with a 482VS Ranger and tandem axle trailer attached. I have no problem moving this rig with the 5.3liter v8. While towing the boat I mostly avg. 14-14.5mpg. That's while maintaining 60mph on 2 lane and 65mph on interstates. I have heard of quite a few transmission problems with GM products, though I have not experienced this. My truck is living proof that if you meticulously maintain your vehicle with preventative maintenance, they will last. I change the fluids in the rearends and transfer case every 2 years, while changing the fluid in the transmission every year, and change the transmission filter every 2 years. I don't think that it is really necessary to go with anything more than a 5.3 liter, as long as you have the 3:63 gear. Any more gear than that will decrease your fuel economy by 3-4 mpg. Hope this helps. Gary.  | |
