In case someone else is looking, I can recommend the following source (no financial or other interest on my part).
A while back, Alan kindly gave me a heads up that Andersen is raising the price of the Andersen Ultimate hitch. He had shared the link where he got the old (lower) price for the gooseneck version, but I found an alternate site which had a very attractive price ($504 - delivered) for the rail version - model 3200. Other sources are selling it for $700+.
One word of warning - I placed the order in Feb, but the stocks are low and they had difficulty getting the distributor to fill the order. They were offered to cancel, if I found it elsewhere. I persisted with them and received the hitch today. To my surprise, they still have the old price on the website. So, it is worth a shot if you are in the market but do not have a very tight delivery window.
I share it here as it is a very attractive price...
