We have a large crate/kennel that we use sometimes to transport some of our goats in the back of our pick-up truck. Sometimes we don't feel like puting the topper on the truck but we found a neat thing to use to cover the crate & reduce wind. We have a thick canvas grill cover that fits nicely over the kennel & then we just run a strap around it--it doesn't flap around like a noisy tarp would. Anyhow, just thought I'd share our idea. This time of year depending on where you live you can find the grill covers pretty cheap.
