2010 Rear TSB or Not??

I've got a 2010 TRD Sport 4x4, DC, LB with the 3 leaf pack. I figured I would need the rear TSB but never really had a load in the bed until today. I had 20ea. 40lb bags of pellet stove pellets totaling 800lbs in the bed and 2 adults and 2 kids in the cab totaling 460lbs for a grand total of 1260lbs. The bed dropped some but not too bad, with the back just a little lower than the front. I drove 90 miles this way and the ride wasn't bad and didn't feel it compress to the bump stops. What exactly does the harsh ride feel like? It felt pretty normal but I could tell I had a load in it. I am just debating whether I should pursue the TSB? Any thoughts or input??
