I've owned six RVs so far. I would rate their quality like this.
1. Arctic Fox - Northwood Manufacturing (Pickup camper) No problems
2. Wolf Creek - Northwood Manufacturing (Pickup camper) No problems
3. Lance (Pickup camper) No problems
4. Dune Chaser - Mckenzie (toy hauler) Minimal problems
5. Weekend Warrior (toy hauler) Frequent problems
6. Forrest River Forrester (class C) Constant never ending problems, typically $3000 to $4000 every year in repairs.
I won't buy another Forrest River product, the quality is just terrible. So keep that brand off of your list.
