Unit has been very well maintained with scheduled oil changes on both engine and generator. Scheduled maintenance included roof treatment twice a year and weekly slide seal lubrication. No issues driving, very solid with drives to the midwest and Illinois. I can tow up to 7,500 LBS since it's maximum GVR is 22,500. Every system function well and includes a Dish Satellite PL7,000 Playmaker antenna, Winegard Connect 2.0 4G LTE antenna and a Wireless WeBoost Drive X Phone Booster plus two TV sets. The unit comes with a Bigfoot leveling system valued $3,000 that was added in addition to Slide toppers to protect the slides. The house battery was upgraded to AGM as well. Tires have TPMS Tire minder system and a RoadMaster front Steering Stabilizer.
