HERE is a link to towables from way back when to current times.
By the way, Welcome to the Forums!
Excluding some of the curmudgeons on here, we're a pretty nice group or RV fanatics. So to summarize what has been said, it is not recommended to tow a Titan Four Down. The transmission and transfer case will most likely be damaged and repairs will be expensive.
I don't remember seeing a description of your RV in your posts or signature. Without that info, the best one can do is tell you to check on the ability of your RV to tow that much weight and to check your receiver hitch to see what class it is, if I remember correctly a class III is only good to 5000#. Your truck can easily exceed that.
To answer the intent of your question, you need a set of baseplates, adapters and a towbar with all of the safety cables etc and of course in some way wire the lights to mimic the RV's lights. And then you will need an auxiliary braking system, a towed of 5 to 7K pounds added to the weight of your rig is going to make stopping much harder.
I did a cursory search for base plates and didn't find any company making them.
Good Luck in your quest.
