Can anyone help me find out where to get an insulation kit for our 2004 Dodge Sprinter 158" High Roof Van? I was going to order from sprinteraccessories.com but they are out of stock until the fall. The price they had on their website was $290.00 which I thought was a great deal. It's fixing to be summer in Texas and I'd like to insulate our new van before it gets too hot. Thanks!
