Actually I used the Reese puck setup for the '03 Ram. As such, I'm hosed as far as using the old Signature since Reese confirmed that they do not make a puck style picture frame adapter.
I've decided, and thank you for everyone's input, to pull the trigger on the B&W Turnover Ball receiver along with the RVK3500 Companion hitch.
The torquing and loosening of the bolt each time to install/uninstall the hitch seems like a little hassle but no one seems to mind and I'm sure I'll get used to it and love the hitch as all seem to.
Thanks again for all of the input.
Happy camping and safe travels to all.
