Here in CA, you must have 6" between the floor and the top of the cut down doors, on the road.It is illegal to be on the highway w/o doors. A buddy of mine was stopped by the CHP, and the officer actually measured them, fortunately my buddy had made them the right hieght by accident(never looked into the legality of them). I personally do not like the looks of tube doors, they don't look finished. As mentioned you will want a way to keep out the weather, in August it can get pretty cold in the Sierra's. On our way to the Rubicon clean-up, the guys with tube doors had to wear heavy jackets to keep from freezing while on the highway, the guys with half doors didn't fair much better. <img src="/forums/images/graemlins/cheers.gif" alt="" />
