Being that you are in Colorado, you may want to look for a used
Little Joe. They were made in Henderson, Colorado until recently and I think most of them were
sold West of the Mississippi. They are a solid trailer and tow well behind a small car.
We tow ours, a 2008 with the 2014 2.5 Outback. You would want to check your Outback owners manual for your towing limits. One important point; the 2014 models like ours had an increased towing
weight, 2700 lb, if the trailer was equipped with
brakes. I recommend
brakes in any case. Our trailer loaded comes in about 1760 lbs.
I'm sure it's been said already, but be leery of weights. The listed weights are usually for a base model before accessories are added.
You can look at the current version, the third iteration of the Litehouse/Little Joe here:

They are said to be building the trailer with the same molds with some modifications.
Good luck in your search. Have the money ready when you go look at used trailers, and be ready to strike fast because fiberglass trailers sell quickly. Ask anyone here.
Last but not least, you can see a floor plan of the
Little Joe here.
