frame question

im bout to start my stock floor frame and i have a question would taking some 2x2 1/4in thick be good enough if i lay it on the inside of the frame then cut the top have off the original frame then weld it all up together or do i need to run 2 pieces on each side by the way its a extended cab ranger thanks in advance

It will flex alot.

Why not just run 2x3? It will be less work than doubling up on the 2x2 in the end, cleaner too.

There is a lot more going on than just running one or two or maybe some 2x3 instead. I have seen some sketchy stuff work, but I'm not a fan of any of it. Even on the Taco that we did with the 2 pieces of 2x3x.188 the chassis flexed a lot!

I didn't do a very good job at being clear in my above post but I meant 2x3 with the 3 inch side vertical, not horizontal. There should be room for it to fit under the cab like that.

2x3 run so that it is 3" tall would be fine.
