After looking over the available options (dusty dog $$$$$) I decided to just build my own, cost was $25 dollars.
Base is a 1/2inch plywood with screwed 2x4's around the edge. Side are 2x4's screwed together. One end has a lower brace so the dog can jump in/out with a berm of dirt on that side. I then tie a rop across the top end so he doesn't decide to jump out after a squirrel or deer.
Went for a 25 mile logging road ride and it works great. Added bonus it acts like a back rest as well. Going to track down some dense foam to glue to area behind by back.
