Fifth wheel pin box extension
Are there any drawbacks of adding a ten inch pin box extension to a montana 3791?

A longer pin box will not give you 90 deg. It will only give you a couple of more degrees. If you want to go 90 deg. you will have to get a slider hitch. Measure from the kingpin to the corner of your coach, then measure from the rear window of your truck to the center of the fifth wheel, then measure from where you feel a longer pin box would take you and you'll see what I mean, you don't gain much. 1/2 the width of your trailer has to be longer than the distance from your rear window to the fifth wheel to get 90 degrees, that's what a slider hitch gives you..
