Yeah, vgreen said it well. Locking and unlocking the hubs is really no big deal. When i get to the trail I turn them on, and when leaving I turn them off. I did notice a slight increase in MPG since putting them on.
And nwoods to answer your qs,
As far as suspension, my plans are to crank the torsion bars to raise the front. (cant believe I still haven't done that). In the back will add a Toyota Sequoia spring spacer. Eventually planning to add KYB Monomax shocks. The sway bar is still on, will delete that as well.
The rear bumper I took off bacause the factory one was too bulky and sticking out too much. Right now Im working on designing a rear bumper that will most likely bend around to the lower quarter panels.
Right now with the 33s and newley installed hubs Im getting solid 16 MPG, before was getting no more than 14.5.
As far as craigslist, I use www.searchtempest.com. It covers all of the surroundings Craigslist communities with one search. Most are all local, I do check in with ebay sometimes. Thats where I bought the fog-lights covers for the ARB bumper, paid $30. Those things are about $200 from ARB.
