I do FLYBALL with 3 of my 4 dogs. I got an E again cuz I wanted the dogs to have more room than a doublecab pickup gave them. I took the two back seats out, put some pads down and put in a large 36" wire crate in the very rear with a seperator in it too keep my two rat terriers (Kidd Roo and Nitro) from fighting in it. Then I put a bed down behind my driver seat for my 65 pound Greyhound mix. The other side behind he passegner seat will hold my other crates, x-pen, umbrella, chair and doggie gear bag. That stuff will be bungied so it doesn't fall over and hit the greyhound mix, Sparky. So far so good.
