Greetings everyone! I am new to the forum, joined out of pure frustration! I have read and checked out many, many, many of the threads on here about Aerodynamic lids for trucks. I saved templates of various types. My issue is no matter what I have done, the tail end of the template shows only a couple inches off the tailgate. I have a 2005 Dodge Ram 2500 Regular cab, long box. The wheel base is 140 inches. The back of the cab starts to decline just above the back edge of the door. I have spent about a dozen hours with the template but it comes out wrong. The truck sits tail end up a bit. If I use the template, I got almost nothing at the tailgate. If I do it with the bed of the truck dead horizontal I only get what appears to be a few inches about the tailgate, which is past the 13.5 mark, maybe almost 14. I think if the truck was done this way, the nose sitting lower would give about 12.5 in the end. I thought in reading somewhere, it is suppose to be 5" or 7" taller than the tailgate. Any help would be appreciated. In advance, thank you all for the sharing of information. The builds, information, as well as inspiration by Bondo, Swede, Aerohead, ChazInMT and others makes my hopes of just 1.5MPG more seem very reasonable. - Vajra
