120 over gvwr is pretty good.
You'll find that it is quite common for folks in here to ignore gvwr and just use combined axle ratings. Some will even just say "rear axle is rated for 10,000 by its manufacturer so put bigger tires on it and pile it on."
GVWR is taxable number and has very loose connection to truck capacities.
With TC rear axle weigh rating is the only that really matters.
Once you weigh it and read the label, you know what camper you can slide on it.
Obviously you will always find guys who go overboard and they apply dually axle capacity to SRW, just becouse the axle has the same model number.
But the same model number comes with different gears, different shafts and different bearings.
