I rarely see them around SE PA, either.  I get a LOT of attention with the TC.  People do double-takes, stop and look at it, walk around it...
We went to several local RV shows looking for TCs before we bought.  Even the dealers 'never heard' of a TC.  At a show in NJ, a dealer told me (true story):  "we don't carry those - there's just no market for them.  Everyone wants a trailer... Oh wait, I remember we took one as a trade once - boy that thing started a bidding war."
...  
Uh, that's the opposite of "no market for them", isn't it?
We finally saw a Maverick at a show in PA - people were mobbing it, amazed that such a thing existed.  One lady climbed the steps and loudly proclaimed, "oh my God - it's like an RV in here!!"
