Tow 8k, Need Weight Dist Hitch?

[hotstang46`]

I do still have the the spare, in fact it matches the rest of the wheels and has a 22with a 38.5in bfg on it. But what is the need for an extension, I've towed my boats around with nothing but a drop hitch, no extension or anything.

Also, I'm having problems finding a company with a wd hitch that has a large enough drop shank, any idea who has one?
