Hi, I'm new to popup camping and now have a used 2000 Jayco popup. It seems to be missing some type of part that attaches the canvas to the side of the door to seal it up correctly. There should be one for each side. My wife and I have been camping and have sealed it up with tape a couple of times but its not a long term solution. Anyone know where I could get this part or another solution to fix the problem? Also, my Jayco Popup camper has a AC unit on top. It seems to have a heater setting but someone told me that some models don't have it installed. I've messed with it and haven't gotten any heat out of the unit. Is there some part I need to order? If so, where and how much does it cost? Thanks for the help!
