This is not the answer you are probably looking for. But, 33 feet of trailer is a lot for the Toyota, space shuttle aside, and you will likely not see much difference between a 27 foot trailer that is more like 29-30 feet in towing. In some applications, like backing up, the shorter the trailer the harder it is. My suggesting is to find a bigger tow vehicle and the entire world of towing will be much more fun and easier. Keep the trailer if you like it and match it with a stouter tow vehicle.
Well said. Going a few feet shorter is not going to solve your, "hard tow."
