I have a Rockwood Mini Lite 2104 which I tow with my '04 Nissan XTerra 4X4. It has a supercharger, which helps.
Even fully loaded, the trailer weighs in at under 5000#, so I'm good to go.
I did have the largest transmission cooler I could get installed. It's not that expensive and is a real good idea.
The TT has the Murphy bed option. In case you don't know, that's a bed that folds up at the head. This one folds against the front slanted wall, and the couch underneath pushes back as the backrest folds up, opening up a nice bit of floor space that would otherwise be taken up by the bed. And what 22' TT has a full size living room type couch?
I don't think they made this exact model this year. Mine is a '13. the '14 is differently laid out, and has a slide out. I like mine better, as this new model doesn't seem to have the Murphy Bed option and the couch.
We love it. It's pretty easy to convert from living to sleeping mode, and vice-versa, and gives us more living space than many larger, heavier trailers do.
This version even has a bathtub, which, though small, is large enough to sit in, and it allows you to lean over and wash your hair without splashing out on the floor.
We convert our dinette into a kid bed for our boxers at night, also.
Though there is no pass through storage in the front two storage compartments, there is a large space under the couch that we use. We have four long, less than 10 inch tall, and about a foot and a half wide plastic bins that we slide out like drawers that provide a large amount of storage.
