Jerred: BTW: the bottom of the 2.5 inch hitch mount on my truck is 22.5 inches off the ground. So, I don't know how much I need to drop my hitch for my trailer. Both the truck (2022 RAM 2500 diesel) and trailer ( 2019 Sport Trek Touring Edition STT343VIK) is new to me. Never towed it before. I'm open to suggestion on drop amount. But, I do need a 16 inch long Shank as I need to leave my tailgate open for an ATV in the bed. Jeff

@JeffS Congrats on the new toys! The Equal-i-zer Weight Dist Shank item # FA28FR is going to be the longest and most drop option for a 2-1/2" shank. It's 16" long and has 6" of drop. What weight distribution system do you currently have? If you could get me some information off of it, I can confirm your bolt hole spacing.
