2016 Northstar Arrow U 8.5. We bought this new, and it has been cared for meticulously. I have done the seals every year, flushed water tank twice a year, and disinfected water holding tank annually. This unit has the cassette toilet, which is a great feature for boondock camping. Upgrades include a 120w solar panel, solar charger, duel group 27 agm batteries. Has tv and DVD/CD Player upgrade. Batteries are taken out every winter and still have lots of life. Water heater is gas/electric. Refrigerator is gas/electric. Some dishes included. Two covers included. We took out the microwave for an additional cabinet. I still have the microwave that came with it, and to install is very simple if you want that option. I hate to see it go but do not use it much anymore. These northstars are built like tanks!
