"Axle shafts and bearings are no bigger today than they were 30 years ago. I'm not sure what year 3/4 ton Chevy you're talking about, and whether we're talking about a 6 or 8 lug 3/4 ton, but it is very likely that is not the case. GCWR might have increased because engines have more power than ever, but that simply does not tell the whole story about the vehicle's capability."
2004 Chevy 2500 Payload 3000 lbs. towing 10,300 lbs. 8 lug
2015 Ford F150 Payload 2800 lbs. towing 11,800 lbs.
I agree with the axle shafts and bearings being the same. But with the evolution of engines and multi gear transmissions towing capabilities of 1/2 ton trucks like the OP have gone way up. Likewise the capabilities of 3/4 and 1 ton trucks have gone up. My 1984 Ford F250 Diesel couldn't even hold a candle to my 2005 Ford F250.
I think the OP combination might be a little long and a little heavy on the tongue weight but the fact that he is asking probable means that he will approach the first tow with caution and will make adjustments from the advice received here as well as from the experiences gained from towing.
I also agree with Dutchmen's concerns about doubt but if I shied away from everything I doubted I would have missed a lot of good experiences. Heek I wouldn't have had all these wonderful years with my DW. :):):)
