My cage took me like 2 months of work. I think 2 days may be a bit optimistic!!

If I were going to do an internal one I would take off the dash completely and weld flat bar directly to the bulkhead straight down from the outer bars. Then I would integrate that with tube in the footwell into the outrigger. Then put a bar right on top of the dash. The result would be no loss in interior space at all and a very strong cage that you could build with a spreader bar. It would be a lot of work but would be just as strong as a standard cage (should be). Of course, with an internal cage if you do ever roll your going to total so much of the truck that an exo may be worth reconsidering.

All good points. An interior cage is easy to do, with some challenges up front as we all have addressed. The only issue with the exterior cage is that it is really easy mess up and make it retarded looking. If I go that route I will copy the NAS cage lines, but the issue is the tightness of the bends that ECR brought up. Then you have to consider mounting the cage to the body, then continuing the cage on the inside and eventually tieing it to something solid.

I do like your point that an interior cage will only save the occupants, but trash the body. Now you have me thinking.

Ahh... the dilemmas!

The NAS cage is 1.5" diameter tubing, right?

I can get 4.5, 5.5, and 6.5 inch radious dies for 1.5" tubing for my bender.

ECR or Cirbo, what is best for 1.5" tubing to get close to SDs look? 4.5 or 5.5?

I used 1.75 inch DOM on both cages. I don't know that I would go 1.5

Exterior cage? I think anything above 1.5" might start to look too beefy. If I did an interior cage it would be 2"

The windshield frame and over-door bars are 1.75". I believe the bar across the vents may be 1.5.

But isn't the exterior cage on the defenders considered weak?

In my opinion, yes, mainly due to thin wall and bolt together design. If you build a well-designed cage out of 1.5 or 1.75 steel and make it integral to the top and tie it into the frame, you should be good. The exterior cage for me is more for keeping the top from collapsing, protecting the body, and a means to carry gear on the top. 2" might be a little excessive on the exterior.

The NAS cage is considered weak by guys like Buck who expect a cage to work more than once. As long as it keeps my skull from getting crushed then its a good cage. Your interior cage, no matter how strong, isnt any better than one-shot exterior cage since your body is trashed in the event of a roll-over anyway.

I think that the supports under the windshield bar (up against the bulkhead) are the first to give on a roll causing extensive front wing/body damage. I believe it was Shane B. who pulled the supports and welded extra metal to stiffen them.

Thanks for thinking of me!

2in is totally unnecessary. 1.75x.120 Dom or chrom will be more than enough to survive multiple rolls.

not to mention it'd look the light light bar on an F150 redneck edition.
