really what you need to do is decide what kind of wheeling you want to do.
have you ever wheeled before??
If you really want to do "basic" stuff for a good long while like you seem to be pointing to now, then a simple, cheap spacer lift and 33's will last you quite a while.
I would honestly never advise going with a 32 for a truck you plan to wheel, for no better reason than the 33 fits with a larger lift and youre already shelling out the cash.
So, imo, if I were you I would put a 2.5-3" spacer lift in with 33's and call it good till I figured out what to do next.
Sliders should also be put on sooner than later because you will hate yourself if you land on a rock and dent your rockers. That tends to happen even when you least expect, too!
Then you'll start to worry about other protection, like skid plates (bud built) and bumpers... front is a wide range of options, rear as far as I can tell, is a limited field.
Then you'll start wanting more height because all this armor brought your rig down a bit, and you've gotten used to 3" and 33's, so you'll start considering pricier options that give you more flex, you'll detach your swaybar, etc etc etc.
THAT'S when you'll start to have real plans.
can you tell I've been here before
