For everyone asking, my payload is 1750 so my truck actually has pretty high payload considering all the options the truck has! And as far as mods go, really the only mods that added any noticeable amount of weight is the bed cover (around 80lbs), the steps (not sure but I think 50lbs), and the front skid plate probably like 25lbs. I don’t see how wheels and tires would subtract from payload because it’s not adding any weight to the truck, it’s what’s supporting the truck lol. I could be wrong but logically I just don’t see how that would eat into payload. So assuming I still have 1550lbs of payload after and a 12% tongue weight on 7500lb trailer that still leaves me with 650lbs of payload left over. Me and my girl & dog weigh around 350, so still 300lb left over which more than accounts for any other weight I’ve added to the truck with little stuff.
