Hey Grigg, sorry for taking long to get back to you. Have been busy with the truck.
I ended up ordering two 4" x 3" x 12' White Oak beams that I am going to put between the chassis and the frame I am building. From there I am going to U Bolt everything to the frame (sandwich the white oak beams) and then also add some brackets with bolts on the side of the chassis to give it some torsional relief - here's an example of what I am talking about:

https://www.macktrucks.com/-/media/files/body-builder/manuals/mack-section-0.pdfI have to source some good long U-bolts. Trying to find out where I can source them from.
Attached are some images of my progress so far. The welder I am using has worked great, it's an Eastwood MP200i and I am using it to MIG with .030 wire. I are using 2" x 2" x 1/4" steel for the base the oven is going to sit on, beveling all edges before joining them.
I also put the deposit down on my wood fired oven so that will be coming in about two months Have to get this frame complete within the next few weeks.
