Welcome to the Gulf Stream Owners RV Forum!
I don't know how far it is from your home, but Martinsburg RV in PA has 4 Streamlites in their lot. Martinsburg RV is what I consider the best Gulf Stream dealer anywhere. They will give you the best deal/price and will beat any other dealer hands down. The also have a terrific service dept.
Here is the link to their website:
