Have you weighed your cargo?

Thanks for all the suggestions about tires and weight of vehicle. I found a stone quarry near me that weighs for no cost. Front axle is 3320 (90 lbs. under (GAWR). My DW is a little bit more than 90 lbs. but we are pretty close. Rear axle is 7280 which is 440 under GAWR. The holding tanks are about 1/3 full Total weight is 10,380 which is about 650 under GAWR. If we travel with empty tanks we should be under Max. even when we add food and beer. I empty the tanks before long trips. I still plan to change out the rubber stems and purchase some sort of extensions for the dually tires. We are also going to Hershey this weekend and will check out even more opinions I am sure!
Anyone staying at Hershy Park Campground (Used to be High Meadow Campground)???
