If I have, it's been a while. It might have been an RV magazine, but I haven't found a HF ad in an RV magazine in a while.
I know Diesel Power only had the 6 ton this time around.
If you're up for a build, search "4x4 tall stands". That should give you some ideas. Otherwise the tall HF underhoist stand [harborfreight.com]
is the basic design I would use.
Cheapways I'd use wood cribbing.
