Tips on the PDI -- make sure the tech who completed the PDI is the one who does the walk thru. Tip 1 - take a lighter with you and light the pilot light and start the oven burners and let them burn for a good 5 minutes. Kill the pilot and repeat the process. Our 2nd TT had a loose gas line fitting behind the oven and the tech missed it on his 2 second lighting of the oven. Our oven just about blew out into the coach on our first trip. Tip 2 - Jayco has the typical stabilizer jack crank and another weird looking crank handle. Our PDI tech had no clue. Found out it fits the power jack on the A frame. Have the tech take off the hot water bypass cover (under the sink) and show you how to use the factory pump to winterize the unit if you're not familiar ( I was clueless). Last tip -- the combo radio/cd/dvd player installed in my Jayco has an AUX setting and an AV jack but when I try to use my IPhone to play my music I get an "Unsupported" error on my phone. Ask the tech why the heck Jayco uses components not compatible with the largest provider of digitalized music. Other than that go have a great time.
