Hey Greg, welcome back! Since we know your 2023 Montana High Country has a Lippert 1116 style pin box the correct Sidewinder replacement you'd need is the part # RP77FR. The correct wedge to use this with your B and W fifth wheel hitch would be the part # SWW-06. Is your Companion hitch a fixed or slider hitch?

Hey Greg, what did you find out about your Companion hitch—did it turn out to be the fixed or slider version? Knowing that could help confirm the right setup for your Sidewinder and wedge combo. Your update could make it easier for others working with a similar Montana and Ram setup.

@Greg right on! With the Sidewinder you'll be able to just leave it forward all the time.

@JamesonC I was going to order that pinbox but the number you gave me is not working or number is not recognized?

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…
