3300-3000=300. You have 300lb margin on your rear axle.
I thought the pin weight was taken at 20% of gross weight not 25%.
12000 x .20= 2400 3300-2400=900
Have you ever actually weighed your 5er fully loaded? Many are 25% pin as my last two DRV's have been.
You and I know DRV's are very nice rigs, however they are also heavier than most. I don't doubt DRV's have 25% pin weights but the OP was not referring to a DRV. I also imagine DRV are at least 5% heavier than most comparable size RV's.
