I tried this once a few years ago and it almost ended very badly. Towing a vehicle that is as heavy as the one you are towing with is unsafe at best. I was only doing about 5 miles per hour and took a turn on a patch of loose gravel going down a very slight hill. The Brat I was towing wanted to keep going straight and I started to jack knife. Luckily I managed to avoid total disaster and pulled out of the turn OK but that was as far as I'd go. I ended up leaving the Brat and coming back for it with a Ford Ranger.
