hitch for flatbed

Here is what I just bought for my flatbed.

Pullrite has a couple of flatbed hitches, one 10.5" and another adjustable 10.5 - 13.5. I have no experience with them.

Check Hensley Trailersaver hitch. They make a 32k low profile hitch that bolts to a plate. Its what I'm thinking of putting on my flatbed.

I built my own frame mounts that attached to the frame same as the factory mounts. My mounts have a drilled steel plate that is flush with the under side of the flat bed deck. The plates have a 1/2 in nuts welded to the under side. The reese cross rails sit on top of deck and bolts down into the nutplates under the deck. Real quick to remove. Used high tensil tall nuts from CAT. Built same set up for my present 2500 p/u

Thanks appreciate the feedback!

I built my bed with a flat deck, no well. My reese 16k was easy to adapt cuz the side mounts are 3" wide. I pitched the reese side mounts and made my own out of 3" square pipe which bolt to the structural steel frame of the bed. I remove the 4 bolts and I have a flat deck. Holland make an awesome primo 5er hitch to use in pockets. Do a search to find it. Craig
I found it.

Industry standard for pin box height is 46-48 inches from the ground for a level fiver. Not many fiver manufacturers publish this anymore.

Thanks the B&w wont fit down in the well where my goose neck is. So i was going to make rails that bolt down and adjust the height so it wouldn't be to tall.

B&W has a flat-bed hitch. Their products are top-notch.

It's not the flat-bed version, but I wrote up a blog post about my Companion hitch:

i believe B&N has a hitch especially for flatbeds.
