I'm wondering if it's the aero of the trailer or the mods on your vehicle that make your experience disappointing. I ask, because I've towed 6000lbs before and it was pretty effortless even through the hills. Albeit it was a car on a tandem car trailer which isn't as much drag.
Are you fully armored with larger tires? It may be that your gearing as a result is just outside of what's good for towing?
