I checked the catalog and the G-2800DXA is rated to support 661# of 
vertical load so the thrust bearing only needs to remove the leverage. 
There is no need for the thrust bearing to support any of the load if 
its less than 661#.

I'm thinking of using the Yaesu G-2800DXA or the Orion  2800PDX which 
will support "1800" pounds and has 17,000" pounds of torque.

73,
