My first 1/2 ton towing trailers was a '67 chevy with a 5600 GVWR 3.73 axle 135 hp 283 v8 two barrel carb with the two speed powerglide tranny. Sure it was slow but it was what it was and I expected that. I mounted a 8' TC on the truck and pulled a 16' 2800 lb fishing boat. Lots of good memories traveling the southern Rockies back then with the kids.
Actual experience is rare anymore around here.
Same here,1957 GMC 1500 and put a 8ft Sturdi Built 8ft TC on it.Re-arched the springs and went camping.Never a problem with anything..
New 1976 Chevy Scottsdale 1500..Put a 8ft Security TC on it coupled with a pair of axle housing mounted coil 3000lb helper springs..That drove and rode great and again,never any related issues,just a lot of fun.
I could go on and on with examples of 1500 series trucks working great for all deeds related to towing and hauling but it would be on deaf ears.
I could say the same for the 3/4 tons I have owned hauling up to a 40 ft Mobile Home without WD system, with the mighty 454 Big Block which had less HP than my current 5.4.I've towed with everything from a Jeep CJ-5 to semi trucks including Kenworth/Western Star/Peterbuilt and yes,even a Mack and it's not the tow vehicle that matters but the driver of that vehicle that counts!
