LCI Air Ride Pin Box Number is 155943 & 158777 for 2020 Keystone Montana 3120RL

Question:

LCI states that either of these Air Ride pinbox numbers will work for me. The 155943 is the direct replacement and the 158777 is the same but a longer pinbox. Is there a benefit to having a longer pinbox? My tow vehicle is a 2019 Chevy 3500HD Diesel Dually. Its on a 2020 Keystone Montana 3120RL.

A longer pin box will give you a bit more turning clearance which is especially helpful if the truck has a short bed. But if the truck is a long bed you wouldn't gain anything significant by going with a longer pin box. That's interesting LCI told you that the only difference between the # LC158777 and the # LC155943 is the length. That's good to know on our end as well.
