uhhh. honestly man you need to know this kind of stuff before you start talking about a SFBD. You dont even need to use 2x2, much less 2x2x1/4. 2x3 will let you lay flat rocker, and 3/16 is plenty thick (the stock frame is 1/8 ) By going to 2x2, you are going to have to redo the tranny tunnel and somehow fit 1 and 7/8" exhaust in that 2" space under the cab. Also, using 2x3 you can reuse the stock body mounts, if you use 2x2 you have make them all new from scratch. You are making a lot more work for yourself than you need to. If the end result is to lay rocker, then use 2x3.
Make it level with the front suspesnion crossmember, it makes the 2" difference between the 5" stock frame and the 3" new frame actually a 2.5 inch drop, which will allow you to fold the pinches.
I admire that you want to do it on your own, but please make sure you understand what a SFBD is and how it should be planned out before you cut. There is only a small difference between a "project" and a "useless pile of scrap", and you will have to cut a LOT of your truck up before you can start welding it back into a truck.
