An electric thermo fan I pulled from a Toyota, is 15amp. It is the same size as a stock sierra fan, but it moves much less air, as it spins much slower.
I would hate to rely on it offroad to keep the car cool on a hot day, let alone some junk aftermarket thermo fan.
The benefit of an electric one, is when its not needed (on the highway etc, its not using power), the downside is, when needed they can not move as much air as mechanical, and will be a lot less efficient at moving air.
For lots of crawling/offroad a mechanical is way better.
For cars on road, an electric is often enough (but they can struggle on really hot days, and a mechanical one is better).
IMO for an off road setup you would need two big oem quality thermo fans to move as much as a vitara fan can, and then package it nicely, and be las light as possible, to give you the efficiency gains you require. The loss of energy when offroad wont be too noticeable, and if one fails, you can limp around on one fan.
On the highway (if the radiator is in the stock location), they will not be required.
Reliability
the sierra solid fan is very reliable, as it has no other parts to fail (doesnt move as much air as vit, and robs more power).
Vit moves more air, a lot more, but needs some attention to ensure the viscous clutch is ok
Electric thermos - most likely to fail when offroad.
For driving through water
the electric can be fitted with an override (which people often forget to turn back on) -And mud usually shortens the life
viscous - can be left alone
sierra solid - I never had a problem in lots of water, but can loosen the fan belt a little if doing water crossings.
A good electric thermo fan setup will probably cost a lot more than a vitara viscous hub fan.
It seems silly to go the more complex, more expensive, and least reliable setup.
