Just a thought... If you end up with just a small area for your dog and are afraid she may fall off, as you travel, you can make a side rail or two that is removable. I have a little medal bracket that these slide into. The real reason i have them is so fence posts and other things don't roll off the back while going uphill but the dogs use them too. And they are easy to remove when i don't need them. I haven't had time to make some for my p5 yet. ...Of course i look like a country bumpkin with them but i guess thats what i am. Haha
