I got the Haul Gauge early this week and sent it back after finding out the Curt Betterweigh has a lifetime warranty, the Haul Gauge only 1 year. Crazy since Curt owns both companies. I was impressed with the device. It was super easy to set up , it detected my VIN and away we went. I know the curb weight of my truck empty, combined with the estimated weight of people, dog and usual gear I carry I think it was pretty dang close. I haven’t had a chance to try it out with the trailer on the bumper yet. I’ll post back on results when I do.
