Congratulations on your first camper!!!! Make sure you have them turn on the furnace and the air conditioner. When we bought our camper, we were virgins too. We failed to have the dealer do those things. Our furnace worked fine but our air conditioner dripped inside terribly. Come to find out, the dealer never took the shipping material out and it was blocking the vents causing it to ice up inside and then drip when the ice melted. Also, have them explain where the valves are and which ones get turned off and which ones stay on when winterizing. When we went to get the camper ready for summer for the first time (bought ours in November and didn't use it until the following spring) It took us over an hour to find where the valves were. We had to remove a bottom kitchen drawer to see them. Then when you have questions after you have your camper, come back here and ask all the questions you need to. This site is chock full of wonderful people willing to help!
