Thanks to everyone before me in the forum including thstone and his original thread here..

I just picked up an 04 6 speed and looking to do a budget overland build as well.
Will post progress here. I do have a trip planned to Moab in June so have 9 weeks to work on it.
This particular X5 is a base model 6 speed, vinyl seats, analog climate control and slick top. Not much luxury so needs to be an overland based on spec.
Progression and ideas
Cragar Soft 8's with LT 265/70R17's (thanks thstone)
Lift kit (undecided on which kit)
Roof Rack - custom extruded aluminum and modular
Hitch mounted tire carrier (Swing out or down haven't decided)
