FORGET THE DRY WEIGHT!!!!!
Look at the trailers GVWR ONLY
Is that number within your toy's weight rating? Don't forget the weight of passengers, and stuff in the truck. That will decrease the trailer towing capacity somewhat. Personally with a short wheel base like the Toyota I would never consider anything that long. I would personally never consider anything longer that about 24/25 feet on any SUV smaller than a 2500 Suburban or Excursion. Sorry
