I say start with recovery, move on to armor and then performance.
Of course this sounds nice but nobody ever sticks to that plan, lol.
Seriously though, start with recovery. You can improve your ride to get into the middle of oblivion but you will need to be just as capable getting back.
Trust me, I wheel by myself most weekends. Nothing worse then that very first moment that you realize you are stuck or broken with no way to take care of it yourself and nobody around for miles.
In particualr I say,
CB (so you can call out if you need help)
Cell phone car charger
at least 1 snatch block but if you wheel alone alot at least 2
Shovel, pick, axe depending on your terrain
Front and rear tow points
Full set of tools
So the nice thing about working on recovery is this will be your excuse to get bumpers since you need it for the winch and tow points. Also, it justifies rockers as you will need jacking points for the hi lift.
Also, justifies new tires as proper tread would be needed.
eh.. it never ends. Just typing this I thought of a million other things you need FIRST, lol
Also, not sure where I got the idea you will be wheeling alone. will you be with people?
