Sounds like a typical bay area tow rig (non diesel, non 4wd)
My experience
I briefly had 93 extended cab 2wd 3500 DRW with the 454cid w/ 107k which I bought for the same reason about 10 years ago for $5k which was a good deal at the time.
It drove ok unloaded and needed the usual front suspension work as well as laundry list of of maintenance items. It also towed ok on the flats but once I hit my first grade it fell on its face and couldn't go any faster the 45mph at WOT in third gear. I ended up averaging 7mpg on that trip and only had three grades that were only three miles long. I was only towing a stock 85 toyota pickup on a regular car trailer. I ended up having to daily drive it and it didnt take long to figure out that I was spending almost $500 a month on gas and this was 10 years ago. I ended up trading it in on a new diesel the following month for less then what I was spending on gasoline.
Sounds overkill for towing a Camaro. You'd be a lot better off getting a 99+ half ton 5.3L, or a later 3/4 ton with the 6.0L because that's what my buddy had (99 1/2 ton) and it smoked me in power, towing, mpg, ride, longevity, ect.
