doctort - Don't know much about the Gulfstream BT Cruiser, but the Trail-Lite has a couch opposite the dinette. In the 2002 model, could get the 211 (without a slide) or the 211S (with slide). We bought the slide unit and the salesman acted surprised when the couch did not touch the dinette. There is quite a gap. Do you have the BT with a slide?
On a slightly different topic, I am planning on installing a fan in the roof opening. What are the arguments for the type of power to get for the fan? (switched from the nearest overhead light or un-switched from a farther away overhead light)
