We purchased this unit less than a year ago when our RV went to the repair shop we have used it four or five times. It is like new condition. It comes with a extended warranty that has four years left on it. The electric jack was replaced when we bought it. We upgraded the toilet to a porcelain bowl.It comes with a 6000 pounds sway bar Leveler and a Tekona Prodigy Wi-Fi electric brake we also upgraded the mattress. This is a really great unit ready to take campus.
