Any concerns about welding weakening the frame? This is a common thing people bring up, but from drilling holes it doesn't seem like the frame is a really high tensile steel.

I am NOT welding on the main chassis frame. I have disconnected the upper 6” secondary frame rail huck bolt joiner plates from the main 8-3/4 chassis frame rail(plates still attached to upper frame will serve as alignment guides). I am converting that upper rail into the floor structure for my habitat build. It will be attached/bolted at the front via a diamond truss where the front crane lift was formerly attached and use captured hydraulic ”springs“ in the rear. I have no concerns whatsoever welding to the new floor frame
