The local dealer is MCD in West Yarmouth, MA. However, they have closed for the season and generally reopen sometime in March or April.

In the past they have brought units to the Springfield, MA and RI RV and Camping shows. But when the factory changed hands several times in the recent past, MCD did not have very many, if any units to demonstrate.
I suggest you contact the factory (
