If your ARB is cycling that often, you have an air leak that needs to be addressed. As mentioned above, mine will go pretty much all day without cycling the compressor.

IMHO, the air vs electric debate is pretty pointless. The electric wire is just as vulnerable as the air line. The fact of having some degree of on-board air negates the extra complexity (which is debatable - the wiring for an elocker is MUCH more complex than that for the ARB)

The big advantage of elocker is that it can be activated manually if necessary (remove actuator, change state of the locker with a prybar/screwdriver, change state of actuator, and reinstall). I have NEVER read a good review of the cable actuator.

The big advantage of ARB is that you have some degree of on-board-air and you don't have to modify your axle housing. Also, since there isn't an elocker for the IFS front. If you want a selectable, ARB is the only option.

When I priced it out, doing a TruTrac in the front, Elocker in the rear + on-board air was more expensive than ARB's front and rear (with the larger compressor "capable" of inflating tires, albeit slowly) since there are package deals on the ARB setup that get you the compressor for free.
