** BUYER BEWARE ** To ANYONE looking to purchase a KEYSTONE MONTANA 5th WHEEL, please BEWARE!! We have experienced our THIRD CATASTROPHIC SUSPENSION FAILURE on our Keystone Montana 3790RD 5th wheel which involved the leaf springs snapping for the THIRD time, which then caused the second axle on the unit to be forcefully jammed up into the the chassis causing significant damage to the underbelly of our unit, along with CUTTING THE BREAK LINES causing us to lose the brakes on our trailer while going down an overpass on a highway. We have been informed by the repair shop that we are EXTREMELY lucky there was not a fatality and that if they repair it, the chances of it happening again are EXTREMELY high and just a matter of time until there is a fatality with the unit. We tried reaching out to Keystone RV and Thor Industries via letter, and all we received was an extremely rude call from the VP of Service Operations, Garrett, telling us our request for assistance was not warranted and that our letter was an "extremely unrealistic expectation and will not happen." He also said that Keystone RV will NOT financially assist in anyway and that we are "absurd" for even asking. Keystone is also fully aware that I had a PICC line in my arm for IV medication and we were stranded on the side of the road for over 6 hours because of their manufacturing defects. We are still stranded, and have been for almost 2 weeks, in the town we were passing through when the incident happened because the repairs are now up to $10,000 and with the safety warning of taking it back on the road, we are extremely concerned. We just want to make sure ANYONE LOOKING TO BUY A KEYSTONE MONTANA 5th WHEEL is aware of what happened to us and the absolute NIGHTMARE we are dealing with because of the terrible manufacturing of our KEYSTONE MONTANA 5th WHEEL. Please travel safe y'all.
