Unless you plan on staying in a place where you don't need four wheel drive, (where is that - the Bonneville Salt Flats?), get a rig that will get to the job no matter what!
The last thing you want to do is get a call out to a good money job that requires a 4x4 rig, and then sit on your sofa wondering how much money you would have made if you had a rig that could of got on location.
It cracks me up when I see these guys up here in Colorado w/ 2 wheel drives. You see them putting chains on and still sliding off the road in sub-arctic temps, or if it sprinkles. They pay a grand for a tow truck to come rescue them from certain frostbite.
I can totally see if you're a highway man, but 90% of my business is via oilfield roads that are maintained for function, not fashion. If it rains, it's bad. If it snows, it's bad. If it blows, it's bad. Generally it's never good..................my 2 cents.
