Something to be aware of. These tend to have very high tongue weights and even higher when you load up. Many of them do not have the capacity to carry much more then a bike and a BBQ. So do check the tongue rating and absolutely get it weighed on CAT scales before you buy. It wasn't that long ago that a member here ran into the weight issue, he was pretty much at capacity without loading his bike on it.
I'd also say the that this style of Toy Hauler never really took off in popularity, so resale might be a bit of a challenge.
While DutchmenSport gave you a list, I don't think many of them are still in production. The Cherokee Wolf Pack 20PACK10 is listed as Dealer Stock only, meaning it's being discontinued. In the main forum you'll find "The Complete List of Toy Haulers" worth checking each manufacturer to see if they offer what you are looking for.
