Just a FYI, but try to keep the trailer as short as you can to meet your needs. I have towed my travel trailer with my Blazer and had plenty of power, but towing a long trailer with a short wheel based SUV is a recipe for white knuckle driving and possible disaster. The longer trailer will try to drive the tow vehicle so you have to stay on top of it every minute. In a windy situation you will be worn out in 50 miles of trying to control it. This is the reason I quickly went to a pick up for towing. It made a night-and-day difference with the extra wheel base and small additional weight.
This is especially a problem if you haul up an down mountains or on interstates with heavy trucks around you a lot. Downhill is the worst as the trailer will try to pass you when you try to slow down.
Get a quality brake unit like a Tekonsha Prodigy and get it set properly before heading out and teach yourself how to use it manually to slow the trailer without braking with the tow vehicle for those long downhill sections where you just need to straighten out the trailer without upsetting the whole rig. You'll understand the first time you get into this situation...

IMHO, you would be best off with a very lightweight, low trailer in around a 16' length if it will handle everything you will need to haul . I definitely wouldn't go over 20' in length with that tow vehicle. The Serpent express is a perfect fit for what you are doing, IMHO.
