We travel with 2 Westies. They only weigh 25 pounds each....Last year they traveled on the couch. We have harnesses that attach to the seat belt. They allow enough room for them to stretch their legs, lay down or sit up.....they usually lay down while traveling. We also have this system in our toad. My fear is if we didn't use some kind of securing system they would become a projectile if we had to stop suddenly or if we were in an accident....We originally had 3 Westies so we used the couch. This year, with only having 2 Westies we have affixed their harness straps to the seat belts at the dinette.... they are like kids...better to keep separated.....
In regards to the a/c.....if it is any hotter out than 85......we have to fire up the generator .
I hope this info is of help to you or another dog lover....This forum has been so good to us in answering questions and helping us to understand the different functions of our Sunseeker.
Take care all....and if you are in Goshen for the rally please look us up!
