The original poster didn't even say his SUV was 4 wheel drive and everyone is saying he should get a winch, skid plates and rock sliders???
A BOV is not necessarily a rock crawler/offroad vehicle for most people.
Ground clearance is useful in a lot of situations where the above recommendations don't come into play.
Sirostac, first decide what capabilities you want before you decide what to bolt onto your new SUV.
Is it 2WD? 4WD? 1500 or 2500?
If you're not interested in doing tha Baja 1000, the vehicle is perfectly usable as a BOV. It holds a lot of gear and people, has some ground clearance and you could probably sleep in it. You didn't mention if you had any family or how far your BOL is.
A front bumper replacement is useful for pushing gates, doors, cars and people out of the way, but if you're just looking to hop on the Interstate to G.O.O.D (get out of dodge) you probably don't need many of those items. Sure they can come in handy, but there are more important things, like first aid kits, food, water and fuel cans for your thirsty vehicle.
Decide what terrain you want to be able to drive over, then decide what extra bolt on parts will help you do that.
Also consider that your truck with $5000 with offroad parts on it will make you stick out a lot more than a plain vehicle that all the soccer moms are driving. That may be a concern if you are stuck on the Interstate in Houston trying to get away from Hurricane X.
