The correct Trailair Air Ride pin box to replace the 1116 on your 2019 Keystone Montana is the part # LC155943 which is rated for up to 21,000 lbs.

When I've reached out to manufacturers in the past they have said that the pin box needs to be an exact replacement and it has everything to do with the design and leverage of the trailer to the pin box. Using a different design could very well damage your towing setup which would likely cost more than the price of a pin box to fix.
