Right now, I have a hammock style seat cover that we use in the back seat of our pickup truck. We never travel more than a few miles with the furbutts, and this works for all of us at the moment. Connor has a terrible habit of chewing any harness used for travel restraint, and Neo is a Houdini that seems to be able to escape any kind of travel harness made! If we put them in travel crates the noise alone might cause an accident, or if we're at a traffic light somebody may think a child is being abused in the truck!
So far, this hammock has worked beautifully!
