I rigged it up for drying originally. They have a nasty habit of bouncing out of the console over the stereo or of sticking my fingers when I go rummaging through the console. But yeah, rip it off the dash, stick it to the vest. Saved my bacon last weekend. I got six hours from town...realized I'd forgotten my box of dries. The one dry I had in the dash patch lasted me the weekend. Caught 20s hand over fist with it for two days.

I could have said the Dana, the air lockers, the snorkel, the winch, the full-float rear end, but really...the fly patch.

The Dana - I'm at a point I'd like a 60 or a custom with Longfields.
The snorkel - I'm generally too tall for most water crossings to be a concern any more.
The winch - I'd go with a 9500 Ti or anything sealed better than a 9000i.
The full float - again, a custom with the disc brackets permanently mounted or a 14b ff.
The air lockers - a rear is overkill; faced with two axles again I'd ARB the front, Detroit the rear.

So, really...the fly patch.
