I have a 2010 Skyline Nomad 2020. Bought it used, very happy with the unit. I did some mods. The frame is very good. The foam walls are nice and quiet. Only real quality issue was a wire pinched under a ground bar, and the sawdust inside the cabinets.
My Mods:
Added rear cargo door
Added Porcelain toilet
Moved the water heater and Added RV generator compartment and honda generator
Replaced dinette with jacknife couch and cabinets
Next mod is replacing furnace with Hydronic heat
