18 321 RSTS axle weight rating

Our 18 321 rsts weighs in at just shy of 10900. After pulling the bearing buddy caps I noticed one outer bearing barely received grease so they will all be redone. What concerns me is the lippert axles are only rated at 6000 pounds a piece. Is this correct because once packed i know the weight is over 12000. Or do they deduct the amount of hitch weight in the bed of the truck? Please give your thoughts.

On 5th wheels pin weight is part of the gvw. On that unit 2 to 3k+ will be on the pin, rest on the axles. Perfectly normal. I'd scale it once you're loaded up and ready to go.

2017 Eagle 293RKDS, factory ordered, lots of mods and upgrades. More than I can list.

Should be a yellow sticker on the door telling you what you have for CCC. Everything else is mute.

I scaled our '18 321RSTS loaded and had 10160# on the trailer axles and 2800# on the hitch (very organized but full storage compartments and empty tanks). Sounds like we are both in the same ball park. Just made a 1400 mile run to Santa Rosa Beach and tire pressure only rose to the 92-94 psi range that everyone else with heavier units are seeing. Had the same skimpy wheel bearing lube situation that you observed too.
