you'll be fine with the 10k gvwr.
funny how these tagging schemes work and vary from state2state.
the last truck was 10k gvwr with a tag/sticker saying "11k or under"
when the new truck (an 13K
gvwr) was registered they simply swapped tags.
no up charge, no new sticker.
so the 13k truck has the same 11k sticker.
apparently registration/tag fees in oz aren't based on gvwr for NONcommerical owners...
and while the total rig is well over 22,000 lbs loaded there is no UPscaled drivers license needed.
maybe it's time to add a big ol' air horn...
