I would recommend a stabilizer hitch too. Remember that 3070 is dry weight, just like jim said once you get gear in - it'll be heavy. I've been to the point where I've weighed EVERYTHING I put in the car and trailer INCLUDING passengers. Most likely you're going to discover you may be overweight.
In addition to the stabilizer hitch, I'd think about a heavy duty transmission cooler for whatever you select to tow with too - you'll be happy you did. Now to go with that tranny cooler, next would be some synthetic transmission fluid. (of course that's just my opinion but my tranny temp gauges always showed them to run a bit cooler with the fluid)
