What tubing did you end up going with? Same as your sliders and bumpers?
No, my sliders and front bumper are made from Sch. 40 pipe bent with a HR kinker. Sch. 40 is measured by the inner diameter. The outer is just smaller than 2" (1.9 IIRC), so I could not use that type of pipe in the bender I am using. I am using 2", .120 wall HREW tube for the cage (and that is what I used for the tubes off the rear bumper too).
Also, are you going back into the passenger compartment at all?
Yeah, I am going to finish the front half completely first, then move on to the rear. I have some ideas in my head for the rear. We will see what I end up doing

....while looking at a lot of pics of other rigs for reference 
just curious why you went with 2" and what it's costing if you don't mind?
