Good info . Im sure other will get help from this topic. I did speak to GM 5500 Engineer Friday. Very knoledgable, he said those have 19000lb springs and they (GM) didnt know of any issue with springs or chassis, but he suspected there was an imbalanced load. He said those upfitters do all kinds of crazy stuff on those chassises. He did say airbags, New spring ($900), additional spring or recurve spring would be acceptable fix. He suggested I contact Gulfstream and see what they said, which I did and still waiting on response. I`ll let you know.
Mile-High, how do you rate the power and fuel consumption? Looks like I`ll be pulling similar load. Thanks
All, how do you rate the overall quality and usability of rig (pros & cons)? Lot of bad about Gulfstream on here. Thanks
