Here's another thread on towing....
Can you really tow 5000+ lbs on 4Runner? - Toyota 4Runner Forum - Largest 4Runner Forum
A few years back my dad got into a wreck driving his full size Chevy Suburban. It was about 75 miles from where we live, piled up in a farmers back field. The tow company wanted about $300+ to tow it home, insurance wouldn't pay, etc, etc.
So he called me up, we hooked up the trailer and off we went to retrieve it.
We had to winch it up on the trailer. It would barely run, front end was messed up. But we strapped it down by the axel's, down tight to the trailer.
It took me about 3+ hours to get home, nice slow pace no hurry. I stopped at the logging scales on the way back. Never really went faster the 45 mph. It liked to push me a little bit, but it was never squirrelly or out of control.
Just under 12,000 lbs!!! Total weight t4r + trailer w/suburban. It was like 11885 or something like that.
As long as you take it slow, think ahead and not get stupid, you call pull quite a bit.
Of course if someone had pulled out in front of me like they did causing my dad's accident to begin with, It would have been a different story. Luckily it all went fine.
