i have about 10k miles towing on my 33 ft tt thought i would check the brakes and pulled drum of to my surprise i only one wheel had any brake lining left i was stopping with only 1 wheel brake ...
No that's not normal. I have a 40' fifthwheel and have over 40,000 cross country mls on it and pads still looked good. I just changed over to disk brakes. I would say you're dragging your brakes or you have too much brake in you brake adjustment in your truck if they wore out that quick
