Going Mudding - Need some Info & Pointers

I have a 12 JKU that will have front & rear trutracs. It has a manual transmission. I may get into some mud and I want to know a couple things.

1. I know being a manual I need to avoid shifting if I'm above my tranny in muck.
2. How high are the differential breather tubes mounted on the 2012?
3. Anything else I need to be aware of as far as maintenance after mudding besides cleaning it off obviously...

Some helpful links:

Maintenance after wheeling questions

Also, it's a good idea to put some hose clamps on the breather tubes to make sure they don't pull loose and let muddy water into your diffs, xfer case and tranny (if you've got an auto).

At some point I thought the 12 routed the differential breathers higher? I can't seem to find confirmation of that anywhere.. hoping someone knows where they go.

Also some people say the Tcase has a breather and the Transmission does not on a manual and Ive seen vice versa which one is it?

Here is what I "think" I have for breathers:

2012 JKU Manual
1. Rear Axle
2. Front Axle
3. Transmission Breather (This runs to under the shifter which can be accessed from inside the vechile under the shifter cover...)
4. Transfer Case (I believe this runs along the transmission to the firewall up halfway into the engine compartment.)

Is this all correct?

Seems like I could probably get bye with just Axles and Transfer case as long as I don't get mud up into my shifter which I don't see myself doing anyway.

Considering putting this onto the axles and the Transfer case: Poly Performance JEEP/TRUCK & BUGGY*::*Steering*::*Power Steering Accessories*::*PSC Vent Bellow - 4X4 Off-Road Parts, JK Synergy Suspension Systems, Fox Racing Shox, Beard, CNC Brakes, Johnny Joints®, Currie Enterprises, Edelbrock, Pit Bull Tires, R

That's all correct, the axle breathers run almost to the top of the fender flares. It's a really easy mod and cheap, need about 25' of fuel line and four hose clamps. I haven't done the tranny (I have a manual also) yet but the others are pretty easy. This is what I would have done if I knew about them first.

I am thinking I could use 3 of the accordion vents. 1 for each axle then i could cut the vent tube for the transfer case and put a vent onto it at that point. I don't think I'll need to do the transmission since it really would have to get up to the shifter inside which wont be an issue for me.
