I guess we got our AF just in time. It was discounted pretty good in early 2019. I started to put a superhitch on my F450 but the Torklift Cannons hit the market and it works fine in my 3" stock hitch.
I have had no issues with my 2018/19 circa AF1140. Its well built and as I have been switching over to a big inverter and lithium batteries, I got to look over the wiring. Wires are well secured and bundled where in some I have seen spaghetti. Put about 20k miles on it so far. Not coming apart anywhere I can see. We do store it in out of the weather.
Good luck on your search.
