I know a lot of people do that and it's better then when there's no topper. I'm just more into seat belts or carries in the car for my guys, but sometimes things can't work out that way, so you do you best to make then safe what ever way you can.

But my worry is what happens to the dogs if you have to slam on your brakes for some reason? They get slamed up on the side of the truck bed. Ouch! My friend drives her Newt around in the bed of her truck, now. In a nice pin with welded brackets to keep the pin sercure, because she learned the hard way. Things happen. When it comes down to it a little slam in the pin is better then being thrown around one end of the truck to the other.

I have seen trucks with fans set up for the dogs and if you put them in their carrier, I don't see any real big problem with it. You Have to have good fans though.

Make you a little bed back there too and you all will have a nice cool ride to Ohio. You know you'll want to be with them.
