How many out there have cats that travel in their RVs?

We have taken all of our cats with us over the years. Our current 2 travel quite well. You know they are part of the family when as you look at coaches you are commenting back and forth where the litter boxes would fit and where to put the food & water dishes!
Our current 2 were both older cats (9 yrs old)at the shelter when we adopted them. One enjoys hanging out as we go down the road and the other hides in a covered cat Bed.
