I took my MH to a CAT scale, the front axle is 6020 lb, rear axle 9770 lb, (total 15790 lb). I looked at that Goodyear chart and not sure if I’m reading it right, the best I can figure out is they are telling me to run at 110 psi. So, 82 psi or 110 psi?

The tire charts list weight per tire location (corner weights). Take your axle weight and divide by 2. Your front will be 3010 and rear will be 4885. Looking at the Goodyear chart your front pressure for single wheel should be 80 PSI and the rear for dual should be 110.
You might want to verify the weight rating of your tires because your rear corner weights are not listed on the Goodyear chart. You may not have an adequate tire for the rear axle weight (optimal words being "may not").
