I have a 2003 Gulfstream Sun Voyager Model 8368 MXG 37' class A. The front slide seems to have dropped about 1" in the rear. I can tell from the accent stripes. This is with the slide closed. The slid...
You have an issue if the stripes no-longer match. I would go to a dealer/RV shop and have them take a look. I'm guessing something broke, rotted, or rusted out. Either way I would not run the slide out prior to getting a second opinion in a controlled environment.
