So this is normal? Front inside pads were destroyed, just turned 35K? Very little towing (maybe 1K miles towing camper and 1k towing landscape trailer - no brakes at 3K #s), but swapped to mud tires at 28K miles. So I am guessing the heavier tires and the towing had something to do with it, but the brake squeelers never made a noise, and the rotors were toast.
