I have a 12-ton for the front and a 20-ton for the rear, and they seem decent for the price. Are they as good as a made-in-USA jack - no, of course not, but they are OK for occasional use.
The two jacks I have lift only between 7 and 8 inches, so you will need lots of sturdy wood cribbing or hardwood blocks to lift your bus a useful amount. In the next few weeks I will need to slide my water tanks under my bus to install them, so I'll lift one side at a time about 12 to 14 inches. This will take two lifts with my jacks, blocking the bus up along the way. Should be fun!
Thanks for your reply, and I have been following your conversion. You dont see many Crown Supercoach II's.
I just need to jack it up enough to get the front wheels loose so that I can fully rotate the steering wheel in both directions a handful of times.
