Skid Row doesn't require you to drop the tank, fits right over the stock skid. That is what I'm currently running.
If you want a gastank skid with more clearence go with a Kilby but 03 or newer Jeeps require a body lift. Also, I'm pretty sure you have to drop the gastank in order to install it, I could be wrong though. Perhaps someone with more experience with the Kilby could chime in here.
Great site to read about and review Jeep related products.
