How to adjust 2010 montana high country slideout

Is this the system with the cables on the side? If so, they should, via a system of pulleys, be routed to the top of the slide on the inside of the coach. There you will see a few adjustment points. Before you do that, have you lubed the slide seals? If not, use 100% silicone spray and lube the seals good. The seals can get tacky and grab the slide making it jump when in motion. You will also want to mark the adjustment bolt before making any adjustments just incase you need to go back to the original setting.
