I was looking at a TT Arctic Fox and a Nash TT. I believe it was a 27E model. I saw a sticker that said Libbert on the axle. Hopefully I'm wrong it was another trailer on their lot, but it shocked me to see that sticker on the axle which is why I remembered it so well. I also looked at the Nash 26Z2 while I was there.
Brad, I stand corrected. I just spoke to Ted, one of the factory reps for Northwood Mfg. He said that they do use Lippert axles on some of the Nash TT. He also said that Lippert are American made in Indiana. All Arctic Fox use Dexter axles. All frames for Nash and AF are made in their own plant.
If you wish, you can call him at 1 800-766-6274. Their reps are friendly and easy to talk too.
The bad news is that they are still using China ST tires. I've been unsuccessful in trying to convince them into using American made LT tires.
