Hello all; back after a year. I am presently working at Oak Ridge National Labs and on site most weeks, so no time for travel. We havea 36" fifth pulled by a 1989 International Cabover, 9spd direct, 855 Cummins 350HP. The truck was bought originally with spring suspension-big mistake. I converted it to air with a rather large ping tank, and the ride now is better than our F-250. Although not as luxurious as most rigs mentioned here, it gets the job done. Like others, I'll never go back-just being able to stop and pull hills is well worth it. Thanks for all the great information...
