No real problems with our dog. He doesn't like the coach moving around when going down the road but he finds his confort spot and pretty much stays there until we get to where we're going. Leaving him alone while we site see hasn't been an issue either. He's not much of a barker and doesn't have much of a seperation issue but be close the blinds just to be sure. Only worry is if there's a power outage during a hot day but we normally open the ceiling vents and turn the fans on even with the AC(s) running just to be sure.
