I have a 2015 precept 31ul, I purchased it in April. It was still almost new 5k miles. I had a serious issue occur on a trip I took last month. I parked and could smell propane. A repairman discovered the line going up to the stove had come down and was resting on the generator exhaust pipe and I had just ran the generator which burnt through the propane line. we were very lucky! in researching how the line came loose discovered the mud flap on the right rear duals on the front behind the generator was only mounted with 3 small self tapping screws 2 had broken off . The plastic mud flap had swung up and knocked the propane line loose. Has any one else had any similar problems. Advice check the mud flap mounting by just opening the generator door and looking at the mud flap. Again we were very lucky!!!
