I have a 94 C1500 ecsb, with a tbi 350, 700r4, and 3.42 gears, plus a towing package. I also have a 86 k10 rclb, that im pulling the motor and tranny out of. im sure its atleast 300 pounds less than stock, due to rust. plus another maybe 800 without the motor and tranny. i have a 16ft tandem axle car hauler. would it be too much for my half ton to pull the trailer and my 86, 25 miles? its mostly back roads, so nothing over 45 mph. im sure itll put a load on my truck, but im not sure if its too much to handle. if i have to, i can try and borrow my dads truck (2000 z71). but that might not be able to happen. any help will be appreciated. thank you.
