Thanks! Yeah, you're probably right about the rooftop A/C. LOL.

I actually have a nice free-standing room A/C unit that I could take along on longer trips during the hot trips so that if/when we plug in at an RV park or at a relative's place with an extension cord, we can have a cool, comfortable environment without using gas. I'm also thinking about one of those canopies that bolts to the side of the roof and you can pull it out so that we have sun/rain protection off the side of the van. Just a thought.
