Hi -
I agree with what you guys are saying. My question is geared towards regular axles not IS. With the increase in axle load you should gain additional cargo capacity. True the tag won’t reflect it and there would be a limitation to how much the frame would handle but I would think that a switch from 7k to 8k axles (and springs) would safely gain you at least 1000lbs of extra cargo vs. the 2000lb increase in actual capacity gained. I’ve been looking at the 3791RD and the rated cargo capacity is2481 but I’ve seen tags stating 1700 of capacity, which isn’t much hence my question around the upgrade.
