50,000 Miles

[Joe.G]

Truck is doing great, still getting 19.5 to 21 mpg on the highway and using 1 qt of oil every 3500 miles. Towed 19 ft flatbed trailer w/cars and 4wd/pickups a few times with no problems, figure mpg was around 12 mpg towing these light loads. I don't keep up with mpg because I'm going to fill her up when I'm empty anyway.

Excellent to hear you have had minimal problems and are still getting such good fuel mileage, I wish I could get that miles per gallon. :rolleyes:

[Joe.G]

Best is w/o the A/C, with the A/C here it ranges from 19.0 to 19.8 and how hard I drive it. The weight of your vehicles really determines your MPG.

Hey joe.G, Have you had any problems with you idler pulley? I've got 28k on mine and I think I see it wobbling like a bearing is going out.

[Joe.G]

No Pullinpower, all my stuff looks good and I check it often due to the miles I drive. Alli-Max can't outrun me!

What have you done to your truck? or is it 100% factory stock?
