We're on our second AF1140. We bought our 2008 brand new 10 yrs ago. It had been hauled over 100k miles and still looked and operated like new when we traded it for a 2018 1140.
We looked at other TCs but kept going back to the AFs.
Northwood is one of the few manufactures that still have three quality control checks
that happen before the units leave the factory.
We didn't have one problem that needed to be addressed at the dealership with our 2008, just regular maintenance and up-keep.
Good luck on your purchase,
Hope you have many enjoyable years with it....I know we did and will with ours.
Rick
