Towing improvement

Hello, I'm surprised at the lack of information shared on improving my 4runner's towing capacity. I plan on visiting our great country attractions without having to buy a huge truck to get there. Got a tested reference?

 

Thanks for your contact. I looked around the posts and have found great discussions.. some a little raw but ' I think we all like a good ride, ,the place I bought the suv checked that too, I hitched up my boat, went to the lake and at the end of the day I had half a dozen cars flash their lights at me cause the front of my toyota had raised up 2 inches and my low beams were to bright.. went to Harbor Freight and bought a special hitch.. took care of that problem now if I can kick my get up and go a notch better I'd be soooo much more confident in passing that farm tractor on a curve while I'm towing our camper.
