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

I'm of the opinion that 90 degrees between truck and fiver is unnecessary. Physics explains that at 90 you cannot move the fiver forward or back, just rotate it about it's center point putting great stress on the suspension, tires, etc. Instead a little extra jockeying back and forth should accomplish any parking need. The truck steering wheel can only turn a max of about 36 degrees so while making a 90 degree turn at full lock, max angle between truck and fiver will be about 45-50 degrees. Finally TT setups cannot jack-knife as sharp as a typical short bed and extended pin box setup. I've never had a problem in 25+ yrs.
To OP, the sidewinder puts less stress on the fiver frame than a longer extension. And the back of the pin box won't hit the tailgate or sides of the truck box.
