Bought an '06 Nash new and upgraded last year from 23 1/2' to 30' Arctic Fox Silver Fox Edition. Both are excellent TT's. The AF I bought last year was an '08 but had, obviously, not been used much. Looked brand new at about half the price of a new one.
Northwood builds quality trailers that are 4 season. They are heavy but, there is a reason for that. They also have large CCC, (cargo carrying capacities)which means with normal loading, you have lots of capacity left on springs, tires and suspension.
Like the Komfort, they have shocks, plywood floors instead of chip board, heavy frames and wood cabinets etc. They actually put wood inside the aluminum framing at attachment points so screws have more than just thin aluminum to bite into and hold. Both are built in Oregon. If you don't have a dealer nearby, Northwood will, often, make arrangements for any warranty work to be done at a repair facility close to you. Their follow up service is very good and well known.
