A 1/2 ton would do the job, I would lean towards a long bed for the wheelbase advantage. (I do tow with my 84 SWB, but it isn’t for everyone).

However, 3/4 tons can be often had cheaper (for square bodies), so I would go with a C20 to get the larger brakes, axle, etc. for less money.

An auto will hold up fine, just put a good cooler on it and drive realistically (not 80mph uphill). A trans temp gauge can also help ensure you don’t do any damage. If you get a 3/4 ton it should have the TH400, which won’t mind towing all day every day.

A stock 350 will tow at 60 all day as well. No need to go crazy, but an LS swap is always nice but not necessary. People have been towing for 50 years with small block chevys and they hold up fine. Not a modern 1000lb*ft diesel, but fine within expectations.

A deeper (higher numberically) rear axle helps in towing. I would recommend 3.73s for your purposes, as you’re not towing a ton of weight, but it’ll help off the line and still keep the rpms reasonable at highway speeds.

All 3/4 ton squares are long wheel base, and the wheelbase helps when towing. If you’re not a C20 LWB fan, K20s can still be had for a reasonable price.
