The first question the salesman ought to ask is “how much money you got?”
Someone linked to Equine Motor Coach. Very nice. There’s a company in Indiana called Showhauler that will build out a horse box on a Class 8 semi chassis. Such builders are around!
I’m still convinced that for the vast majority of horse owners the truck/trailer combo is the most efficient in terms of economy and use.

I would second this. One of the nice things about a truck and LQ trailer is once you get the trailer set up at camp/show/where ever, you have the ability to disconnect the truck and use it to go somewhere. You don’t have this ability with a motor home and trailer or a horse box.
