Conversation Between HouseMouse and Inicter

Good Morning and thank you for the Info on the Weigh Safe... I have a 2017 250 SD. I'll be pulling a horse trailer, being new to this truck I would like to ask you if you could recommend what one I need. I see the different size drops and have gotten a bit confused on all this. I'm thinking the 6" drop but again a bit confused.
