That's ok, I could copy/paste to see it.
I would think it would depend on the dog. I don't think mine would like an inflatable bed because they are wobbly to stand on. Your username suggests yours is a whippet? If so, they tend to feel cold and caravans tend to be chillier than bedrooms and airbeds offer no insulation, making them quite cold to sleep on. Not sure if that might be a factor for your dog?
I would also think it would slowly deflate if you used it long term in the car - like every air bed I've ever slept on has over the course of a night or two
