[TJ's Chevy]

I drive my 64 GMC 3/4 ton all year....all I can say is....Weight....fill that bed with wood, bricks, concrete.....whatever....but get something heavy back there. Also DON'T put wide a** tires on the back and front or you'll make things worse.....deep tread, tall, and skinny.

Keep in mind my 3/4 ton GMC has a 900 pound 305 v6 up front....so I had to at least match that in the rear.
Load of green wood and 32 inch deep tread skinny tires made driving through 3 foot of snow pretty decent....even on black ice it wasn't to bad. Course....my top speed was 20 mph. haha Luckily the roads were ok....but back roads were not plowed. Made for some fun!
