I just bought a 1987 Gulfstream Sunsport 27 ft. It was'nt my first choice, but it did have all updated equipment,and low milage, besides the price was right. I have had large travel trailers in the past, so I'm kinda knowledgeable w/ the rv concept. The few questions I have so far are, can you drive the rv and have the generator run for the AC? That's probobly a stupid question. Second how do people drive in the winter going to Florida without their tanks/pipes freezing up? Or how can I winter camp using the tanks. Lastly, I have a Onan Emerald plus 4000 Gen, the end cap to the muffer looks like is came off, so it is loud, and it discharges the exaust under the rv, I assume the end cap also connects to a extended tailpipe. Where can I find a new muffler, or fix the existing one so that it is safe.
