Weight on tires, one heavy diagonal, one light diagonal

When I first bought my Arctic Fox 811 for my F250, I was fine on tire capacity when just carrying the camper but was withing 50 lbs of tire capacity when also hitched up to my trailer even when I redistributed items to minimize rear axle loading. When I had the chance to go to 19.5's, I jumped to H rated 4805 lb tires and 4500 lb rated rims - I still would check my weight when coming across unattended scales, but I no longer had capacity worries and did this strictly to know how much "stuff" I was accumulating.
