I'm a big guy - 6'4'' - 240 lbs and have owned my 4 Runner sport (with leather seats) for about 1 year. Most of my driving has been for shorter distances. This Christmas I took a 1800 mile road trip. This is by far the longest trip in the new 4 Runner. After driving for about 4 hours, my lower back started to hurt. Then my legs started to hurt. I had to stop every couple of hours to stretch so my back and legs would not cramp up. I tried all of the various seat positions and nothing really seemed to help.

I have read various people trying to "lift" their seat up etc, but I doubt that is going to work. Has anyone had any success with aftermarket seats or swamping their 4 Runner seats out with a Land Cruiser or Lexus? Everything else about my 4 runner I love.

I'm sure other people experience the same thing as me. I did not have this problem in my 97 Jeep Grand Cherokee Limited!!!

Any suggestions would be appreciated.

Thanks
