Hi Mike
There are folks far more experienced than me in the CJA...but I think that al of us would probably agree on the following suggestions:
#1. Make sure that you have recovery points (mounted to the frame, not the bumper) on the front and rear of your rig. If you don't know how to go about that, advertise here on the "Jeep items wanted" board to see if someone has a set of the stock tow points left over from when they installed aftermarket bumpers - or maybe someone local can fab some for you.
#2. If you currently have Mud Terrain (MT) or All Terrain (AT) tires, you don't need to rush into spending a bunch of money on new shoes.
#3. Get yourself a CB. If you go into the CB shop at the Road King truck stop on Barlow, the gent there really does know his stuff.
If you have MT or AT tires, front and rear recovery points, and a CB, then you'll be welcome on most runs. This will let you get out and see what other people are running on their rigs, what works and does not work for certain obstacles, and what parts of off-roading you enjoy the most. Then you can build your rig for the type of off-roading that you like.
None of these mods are "cool" or "sexy"...but they'll get you out on the trail, and won't break the bank.
