Couple more things to think about that are safety related.
Brake system on your escape - does it have 4 wheel disc or front disc/rear drum? Brake fade would be a great concern for me with the disc/drum set up at the gross weight rating. At gross weight of 4520 - a 2500lb. trailer is 55% of gross - in many states this weight percentage will require trailer brakes. I absolutely know that in Washington State this is the case. No trailer brakes in Washington equals a huge liability -if in an accident. Especially if the accident goes over your insurance coverage maximum values.
There is no brake controller provisions on this era of Escape. Yes, one can add it but it will require tapping/running multiple circuits properly and using adequate gauge wiring that includes a power feed for trailer battery(Breakaway system)
Several here have reported towing utility trailers with an Escape. Personally, I would consider towing 2500lbs around town at surface street speed. But, change conditions to highway speed towing in weekend traffic seems a bit sketchy without trailer brakes.
I am not a weight police person or adverse to some risk person, but I would consider all the issues from mechanical to safety before towing with my escape which is a 2005 XLT 3.0 v6 with 4 wheel disc.
