[Help] Transporting Dogs in a pickup truck.

I used to have a large truck with a cap on it. Whenever I took my dogs anywhere, I would put their kennels in the bed. The two kennels fit perfectly side by side and they never moved.I just got myself a new truck, but, I don't have a cap for it, yet. The new truck is smaller than the old one and the kennels won't fit the way they did in the old truck. I am wondering what my best solution is until I can get another cap?I have about 41" between the wheel wells. I could find some narrower wire crates, like what I used in the other truck or should I get some hard plastic crates like what is used for airline transport? It is rare that I have to take them more than 5-10 miles away, but, I may have to take them 60 miles away for boarding soon.Unfortunately, there isn't enough room in the cab for more than one dog at a time. via /r/dogs http://ift.tt/2s7iV1S
