Depends on what it is and how old it is. My old camper (1999) really isn't much different than the new one in how the major stuff works. It is just that the new one has a few newer gadgets and more space.
If you're only on this forum, you might want to join others as well. This is a relatively small RV forum. Yes, you have a Jayco, but you might have more luck with questions posted on larger forums.
I frequent two forums (here and RV.net) and typically post my questions on both.
