BIGFOOT,
I have a 2008 DC Short bed TRD Off Road edition. This is my Daily Driver and GSD transporter, he's big, 113 lbs, 21 months old, and it fits him fine. It replaced a F250 Diesel and We love the size. Perfect in the city and even better on the trails. I have a Leer shell on it and it works perfect for camping, hunting, and GSD training and transport. I made a set of expanded metal mesh covers for the inside of the sliding windows to cover the screen window openings so that he could not poke his head through it or tear it up. These also make the shell more secure. I made a template of the window out of paper that covered the screen half. I made it 1/2' bigger all around so that it matched up with the window mounting screw points. I used a plasma cutter to cut them out of expanded metal mesh screen (diamond shaped openings) and had them sprayed with Line X to keep them from being sharp on the edges and to keep them from rusting. I screwed them in place using longer sheet metal screws with fender washers at various points around the window by removing the origional screws, about every other one where there was an opening in the mesh. The covers are mounted solid, the windows do not leak, are easily opened while providing good protection and ventilation for the GSD and items inside of the bed during shopping or camping trips. I have the suspension and truck set up for overland journeys to include towing an off-road pop-up tent trailer. I really love it and it has not failed me yet. You GSD will be quite comfortable. Good luck with your adventures.
