I have some questions about towing with an 89 22RE that just had a top and front end rebuild. I want to get a small boat and tow it with the yota. I have no idea what it can tow, but it has a new factory bumper rated at 3500. Pulling up the boat ramp, couldn't I use 4 low with the front hubs unlocked? I don't see why not, but I'm not well versed in the 4x4 area.
