NHTSA Complaint #11462558 — 2018 GRAND DESIGN SOLITUDE

One of the passenger side leaf springs on our Dexter axle snapped near the shackle point. Since we have read that this is a common issue, we are reporting as this could have potentially resulted in a serious safety issue. When our leaf spring snapped, it severed the propane line that runs underneath our 5th wheel in two places. It also caused the two tires to rub together. Fortunately, for us, this must have happened within a short distance from the RV park we were staying at for the evening because we only lost about 1/3 tank of propane and the tires do not appear to have sustained significant damage. We were able to disconnect and drive to a nearby trailer supply store and get a new leaf spring. We also removed and took the damaged propane supply line to a nearby propane provider/retail store and have it repaired. My husband replaced the leaf spring and reinstalled the propane line making sure to test for leaks. We did not keep the broken leaf spring as it didn't even occur to us to keep it for inspection but we are able to show where it snapped, if needed. It almost appeared to be rusted from the inside. Since we don't live/store our RV in humidity prone areas, this seemed unusual. This incident occurred while we were on a trip to visit family in Florida. We do not/nor have not lived in our RV full-time. Our use is infrequent. There was no indication that there was any issue while we were driving. It was only when we exited our truck that we smelled a very strong propane smell that my husband investigated the source and discovered the damage. We had been traveling on I-20 near W. Monroe, LA when we discovered the issue. It is frightening to think about what could have happened had we had a blowout from the tires rubbing together, along with the propane leak while driving down the interstate at 65mph. Please note: we are extremely trailer weight conscience and are very careful to not overload.
