Combined truck/trailer?

Someone at my stable, I'm not sure who, has a horse trailer that is a single unit with the truck. It looks sort of like the type of RV in the image below, except that the entire back half is a two-horse trailer, and it's MUCH older.
I can't find any pictures of them on google, but I'm sure I don't know the right terms to search for. Does anyone still make these?

Look for "horse van" that's what they are called. They arent very popular here but I have heard in other countries they are. I've only every used one and it was years ago but I remember it being very nice. There was one for sale locally here a few weeks ago and I know it didn't last long on the market!

Thanks! That's exactly what I'm looking for!

Just wanted to find out more about them. I'm seriously concerned about the ability to "fit" a truck in my apartment complex's small, crowded parking spaces. So wanted to see if this might be a viable option, where I just leave the whole thing at the stable.
