I have read on here for years that a Chevy truck receiver is a basic bolt on. I have been looking for one at junk yards and such. I found a Dodge truck receiver (Mopar sticker on the hitch) for the right price (free) and set to making it work. It was about 8 inches too wide, so I had to cut the ends off and reweld them at the proper distance. I bolted it on and was happy with what I had. 25" from the top of the ball to the ground. The next day I used it to pull my 18' car hauler to go pick up a truck and parts. We probably had about 8,000 pounds on the trailer and about half of that was between the hitch and the front axle of the trailer. We drove 15 miles and stopped for food.
I checked the tie downs on the trailer and noticed the trailer sure did seem low. I got to the hitch and was amazed to see the ball almost touching the pavement. The flat sides of the receiver frame had buckled and the ball end just rotated down. Several bottle jacks along wth the trailer jack got it back up to proper distance. We wrapped about 20 feet of chain around the hitch, pintle hook, shackle mounts and rear bumperettes. That got us home without more problems. The moral here is get a hitch rated for a bunch, don't overload the tongue of the trailer and stop to check things out often.
By the way, the M35A2 pulled the trailer like it wasn't even there.
