Hi, I have a 2009 Aliner Classic & my first winter. I need to put some covering on it and don't know what to order. I took some measurements which I'll list here, maybe someone with experience can suggest what size cover I need. Body width is 6'8" the AC protudes 7" on the one side. so 7'3" including the AC. length is a 12'3" body, add 7" for the spare tire in the back and it is 15' from the back of the Aliner to the battery; 15'7" including tire & battery. The battery & propane are on the A frame leading to the ball, both have enclosures so they don't have to be covered. If they are covered, unless the tarp cover has an appropriate taper for the propane & battery it'll be floppy. I suspect the battery/propane enclosures can be exposed & maintain integrity. With this, what dimension cover should I go for? Snow's a'coming and I'd like to have it tied down & ready with it full of Downy fabric sheets to chase mice. Thanks all!
