bateauman, I might suggest that you take a look at each of the leading builders web page and check the listings for builders in our area. I happen to know and like the Leola folks, and also know Jim at Lehman in Martinsburg, WV (about 2 1/2 hours for you). I am sure the CSC, Hannigan, DFT and others have folks near by as well. I am just not that familure with them at this point.
You might want to check around, however, as I seem to recall some discussion about the possibility of builders not wanting to trike out airbag models. Seems there was some concern about setting off the airbags, but that may have been addressed by now.
Good luck with your search and if you would like to check out a Motor Trike up close, give me a holler as I would be happy to let you give mine a spin. Good luck with your project.:thumbup:
