Driving Skills Because with these, the odds are always in your favor
OTHER: Self Recover skills Because when the odds don't fall in your favor, you want to be able to still move past what ever the obstical is
Articulation Because when your keep your tires on the ground it helps to go forward or backward and reduces the feeling that you need your locker.
OTHER: Armor/Skids Because when your tires just won't touch the ground. You'd rather the ground not touch your transmition, transfercase, oil pan... ect...
Ground Clearance Because even though they can, you would rather the above not touch anything
Tire Height Kind of redundant... Goes with ground clearance
Tire Width Kind of redundant... Goes with Ground Clearance
Tire Tread Because no matter the terrain, if you have good tread on the tires, and they are touching the ground, odds are something is going to move.
Lockers Nice to have but makes it really easy to damage things... Not saying they are bad. But, they are in my opinion a last resort just before winching. You should be able to get over just about anything without them.
Torque Nice to have, but doesn't make a good driver.
Horse Power Wheel spin only damages things!
