This should be a fun journey, I'm all but set to tote a 1,900 lb. U-haul trailer 1,000 miles (VA to AL). I plan on loading around 1,500 lbs into the trailer, and I plan on adding weight into the bed to reduce sway. I have a 2003, 2.7 L, 5 spd, 4x4 xtracab. I have seen a thread or 2 on pulling this specific trailer with the 4 cyl. and would like any additional input. I have read the tacoma towing bible, and found it quite useful, but i'm looking for experiences I am planning to avoid the Shenandoah mountain range by following the coast until I can cut through the Atlanta area.
Oh, and i have a Curt class 3 hitch rated for 7500 lbs (way over the 3500) on the truck.
