I have a 2001 Tacoma, V6, ExtraCab, ARB front bumper, Custom rear bumper and rack. I have been through a couple iterations now and am finally happy. I run the EMU's in the front with the Bilstein 5100's. rears are custom 10 pack Deavers, Ride Rite Airbags (the weak link), and Bilstein 5100's. I just had the Deavers installed a little over a week ago. We decided to leave the air bags on for leveling. I am currently running 20 pounds in the left bag and 10 in the right. I just got back from the WTW Pig Roast and had the opportunity to do some 4 wheeling (Coyote Valley outside of Bishop) before meeting up with everyone. With the new Deaver Leaf springs the air bags can fail and the rig is still easily driveable......just not perfectly level. This is exaclty how I asked Jeff at Deaver to set it up for me. I would not recommend the Dakars or even the standard Deavers....you need to have someone make the spring for the exact weight you are carrying.
