We purchased our first brand new 5th wheel 2 years ago and are about to purchase another new one soon. I plan to make sure everything is in working order: the water pump, hot water heater, slides, heating, A/C, awnings, no leaks anywhere, stove top burners, oven lights. Our last brand new one, the gas line connection to the outdoor kitchen was bent and wouldn't function. We also had a small leak on the hinge of the outdoor kitchen that caused some water damage inside. We ended up just caulking more, but it was something you don't realize until it rains. Unfortunetly, somethings you won't realize until you are actually living/camping in it.
