Newbie needs advice for 1st RV trip in a week.

Fair warning: Buying a used RV and immediately heading out on a trip is a very bad idea. It might go well but odds are there will be things that don't work, things that you can't figure out how to work, and things that you wish you had.

If possible you should spend some time at home in camp driveway before hitting the road with your purchase. This is particularly important with new RVers because it is likely that nothing in the RV is what you expect nor works like you expect.
