I didn't find a lot of people using their 4Runner to tow before I decided to do this and I did find a lot of "get a real truck if you want to tow" sentiment. I went ahead and did this anyhow because it seemed to me that it would be fine if I followed the weight guidelines from Toyota. I bought a Tekonsha 90195 P3 Electronic Brake Controller and a Blue Ok weight distribution hitch to make my towing experience as good as it could be. So far I like the way it tows. I'll post more after some longer trips in case anyone else is thinking of a 4Runner as a tow vehicle.
