Disappointed with the off the shelf options, we opted to design and fabricate our own hitch mounted vice setup. This allowed us to design it in a way that it could also be used with our custom heavy duty adjustable height work stands as well. And let us design around materials we had on hand. Some even from the scrap bin.
We started by cutting and deburring all the needed materials and completed the necessary layouts. All materials are 1/4" thick and normally used in HD hitch applications. No cheap thin walled materials in this build!
