We have used this for the past 4 years to haul water for our cattle but our lease is up and we no longer need to haul water. The truck is automatic/gas with a 366 in it. It has 116,000 miles and runs great. It’s geared to be a puller and isn’t built for speed. It maxes out at 55mph. I believe the water tank is 800 gallons and works great. The air blows but ac doesn’t seem to work and didn’t want to pay to have it fixed. If you need a good solid truck to haul water this is perfect, call me if you have any questions. OBO
