Ya it's crazy what all the gadgets and nonsense electronics weigh. I read an article about it. If you looked behind the dash, or under the hood, or grabbed a seat out of a 1970 truck there just wasnt that much there. Look behind the dash and stuff of a 2020. Its packed with motors and wires and computer boards. Just think how much of that #1500 you could chip away if you stripped the electronics out of a new truck. Plus add in emissions and safety stuff.
It really is amazing what a modern truck can do as far as speed, stopping, towing, etc. Just look at what we demand out of tires now days also. Good or bad, it is amazing.
