Questions Regarding H2 Winches, Portable Air Compressors, Spare Tire Jacks, etc.

What's a good winch system to have for my H2, as I know absolutely nothing about them nor have I ever used one to date? Can one be shared between the the front and the rear receivers, or is it just best to leave it up front? Also, are these things operated from inside the cabin and/or standing alongside the front of the H2 and then being operated by some sort of remote control unit? Also, what winch accessories should I carry; i.e., 'tree saver' sling, chain, tow hooks, etc...just in case?
 
Also, what is the best type of 12 volt portable air compressor to carry in my H2...just in case I need to lower the tire pressure prior to transversing some sand dunes; thus, requiring the need to refill the tires back to normal operating PSI prior to driving back 'on road'?
 
Is the OEM tire/wheel jack appropriate for the H2, or is there something better that many of you carry instead?
 
Also, how badly do items have a tendency to bounce around within the H2's cargo area when one is actually driving 'off-road'...although I plan on taking everything slow and easy? Should everything be tightly secured within the cargo area anyway?
 
Thanks for your help.

Have you seen the WARN PowerPlant Dual Force HP? I haven't seen anything posted about it but it seems made for us offroading! Air Compressor with a WARN winch, just needs a beer tap to be perfect
