Looking for a Spyder adaptor for Pakit Rack for my RT & other questions?

[wifesspyder]

Hi all. I have a Pakit that I purchased for my now gone 2006 Gold Wing. It is brand new and never used. I have the vertical hitch thingy for it for the wing. Anyway, I know that Pakit Rack used to sell an adapter for the Spyder, but I don't see it on their web page anymore. Was this discontinued?? My other concern is that with the hitch and pakit attached right to the rear suspension, that this will exert an awful lot of force on the metal parts of the system, possible resulting in metal fatigue and failure. Also it would pound to death anything in the cooler?? I would have the same concern pulling a trailer I think. Anyway, what is the consensus on all this?? Thanks for looking..........BTW, my Spyder is a 2018 RTL
