Hmm, your title
says "13-17ft", but in the body you say "13-16ft".
If you want to buy a new trailer, forget Trillium
. They are out of business. I don't know if their descendent, Sidekick is in business or not.
If money is no object, you may consider the Nest. I see you are Oregonians and the Nest is built in Bend. At $1.50/mile shipping Nest may be a bargain.
And they do have a membership on this forum.
If you can go a little bigger, the Lil Snoozy
looks to be a good one.
Good luck in your search. It is exciting buying a 'new' trailer.

Whether you think you can or think you can't, you're right.
