Actually, when I started driving I didn't know what O/D was. We ran 2500-3k rpm at 70mph and 2nd gear (passing gear) was the sound that meant power was delivered. Along came O/D for CAFE reasons, not towing. Had nothing to do with power or towing. Then diesels started showing up in pickup trucks and since they couldn't rev, they towed in O/D that was meant for low load fuel efficient cruising. Didn't work out too well. Over the years transmission have been beefed up to accommodate towing in O/D. I went along for the ride. So going back to the way it was before isn't something new, strange or foreign to me. Difference is we now have over 300 HP out of a small block, more fuel efficient, longer lasting engine that runs low rpm empty and "normal" towing rpm while towing. Works for me!
The possibility of a $12k fuel system repair doesn't give me diesel envy but hopefully that's very rare. If 8.5 mpg towing is going to break the bank, 10.5 mpg isn't the solution. It's all about what your priorities are.
