Just to clarify, the OP is wanting:
to tow a 2000# package
and spend like $2000, but able to go to maybe $3000
Although a 7x18, 9990# trailer is a good trailer, it in no way is a good match for his specific case. That trailer will weigh twice his package weight... And it becomes a burden as a general, light, Utility trailer, with his jeep.
While this trailer would "technically" work, although over budget; i dont like the safety margin... I'm also not a fan of aluminum trailers; too hard to repair; but for people in a salt environment, they might be great.
Steel, min width, 6', but I would prefer 6'4", just because; min 14', but 16' is better; 2 front tie downs, 2 rear tie downs; mesh ramp-gate; the ability to remove/lay forward/flat is nice; 2 axles, 3500# each, with atleast 1 set of brakes. Believe it or not, a wood deck is easier to load/unload/walk on, then metal, and should be cheaper, normal, 15 or maybe 16" wheels, painted steel is fine. Avoid 14/14.5/16.5" wheels. A spare is nice, but you can pick up a bolt on spare bracket and a spare wheel-tire after the fact
Used is fine; but consider the cost for 4 tires, lights, deck, and many used ones stop being the "deal" they look like.
