Congratulations! on the new to you Class C. After you have spent several hours watching the YouTube Movies and have some basic understanding of how it works, see if the guy that sold it to you will help with any unknowns that he knows about. Then it is RECOMMENDED you do the driveway weekend camping trip. Do not leave the house. As you cook, eat, sleep, watch TV, or whatever and you need something write it down and go in and get it. Example: forgot the ketchup and a toaster the first time out. Once you have spent the weekend in the driveway, then you can feel a little safe about the 1st real campground trip near home.
FIRST LESSON: Do not plug into the house 110v/20amp and try to run the A/C unit on the roof. The A/C is a 30AMP Unit.......... Start enjoying.
