I am thinking about getting a tube front bumper for my 02 D-Cab. I don't do a lot of rock crawling, but a little romp in the desert is always fun. So here's the question- what is the practical difference between a tube front bumper that requires complete removal off the OEM bumper (like Badland or Demello), and one that allows you to keep most of the OEM bumper (like the ones CBI Offroad makes). I would think that your approach angle could be more aggressive with the ones that require full front OEM bumper removal but maybe I'm dreaming. And I like the looks of keeping part of the OEM bumper more, but besides that, I can think of no other advantages. What does everyone think?
