Hi George,

About the only thing I can add, is I would consider using a 2-1/2" or 3" receiver tube with a 1" or 1-1/4" pin.

I use 2-1/2" custom built receiver with a 3/4" pin and I noticed with my tri-axle flatbed pintel, my pin shows some offset wear after about a years use, maybe 2k miles total OTR use. That's about as close to pin shear as I want to come. I'll be changing to a 1" pin shortly and I use tractor top link pins as they have a nice hole for a pad lock.

I used a 40ton pintel hitch off a semi trailer along with a solid 2-1/2" steel draw bar then made 20" of total adjustment in the ball mount plate, 10" up/down, with a 1/2" x 2" plate gusset. I then use two 5/8" grade 5 bolts to attach either the ball mount head or the pintel head.

When I change the pin too 1", I'll also add 1/4" thick flat washers to either side of the pin hole. This will give me 1/2" total thickness on either side for the receiver pin bearing point. My 3/4" pin wear could be coming from to thinn of bearing point sidewall and not from being overloaded (pin size overload).
