One of the reasons that we have a motorhome is to make it easier to travel with our dog and cat. The cat hates traveling in a car, gets sick and heaves after just a few minutes. But in the Vegas, he jumps up on the bed and crawls under the covers and sleeps until we stop moving.
The dog usually starts the morning on the DW's lap and then moves to floor around her feet. They are great travelers have a good time seeing the country.
