Hokie,
The dunes are between Florence and Coos Bay. I’d guess about 3+ hours southwest of Portland. Not sure of your dune experience, but the oregon dunes are like speed bumps compared to Glamis and Dumont dunes (so-cal transplant, as probably 85% of oregon, or at least california anyway). I have to admit though, they sure are a lot more prettier though. There is also the Christmas Valley dunes southeast of Bend. Never been there yet, but they look pretty cool due to the high desert surroundings.
As far as the lift height, I went with the dakar lift that david from urbanlandcruiers sells. I think it comes as a lift between 2" to 2.5" (maybe david will chime in). After a few emails back and fourth, we figured in order to get the lift and look I wanted, the dakar lift with 1.5" longer shackels than what they normally come with would do the trick. I’d guess it gave me a lift of about 3" to 4". TOY 350 helped and has all the numbers, I’m sure he’ll chime in. Do a search for “dakar lift 1.5" over shackels” or something like that and the thread about it should pop up. Right now I’m waiting to hear back from david (check you email man) about how to keep the smooth ride and bring the front end up level with the rear since there is a slight rake to it right now. I’m sure the heavy ass front bumper and winch contributed to this. I would seriously consider the dakar lift if you are looking for a suspension lift. I’ve been in some bad suspension lifts that did the lifting part ok, but as far as quality of ride, they were like an old wagon with wooden wheels so be careful. Also, the lift install was by far the easiest thing I’ve done so far, just make sure you have at least 2 floor jacks and it’s cake. Good luck.
