Rear disc conversion, is it worth it?

Nothing to add, but in response to gkhashem;

My '69 has drums all around of course and they serve me well, even with a load of gravel down a long grade or coming downhill on a freeway off-ramp. But we don't have weather here, we hardly know what it is actually.

I guess that if he was hauling a big camper or pulling a trailer (or both) in bad weather then disks in back would be an advantage or at least offer a little "peace-of-mind".

The back brakes are very important when you have 3000+ lbs. in the bed.
