Alternator Preference? Dual vs. Heavy Duty

[SoCal66]

Anyone have a preference on running Dual alternators vs. the HD alternator? Assuming Duals provides a level of redundancy but just checking.

Thanks

No opinions? Not likely...

i would go with a single big unit... like this bad boy: '99-'07 Ford F250/350/450 & Excursion Powerstroke TAD 270 Amp SP series alternator

ive been wondering this same thing...

For the rapid heat heater, it is required...my opinion? uhm, if you want a rapid heat heater...? Might want to lean towards accepting having two alternators...

I think this is going to be one of those personal preference deals. From what I've been told, it is slightly more efficient to run one larger unit than two smaller. However, the tradeoff is the benefit of always having a backup.

If you were pulling a trailer with a ton of running lights, triple axle electric brakes, and running power inverters off every cigarette lighter outlet than you may need the doubles.

I prefer dual alt's.... That's what I have on mine

The duals were intended for ambulance use. Unless you have someone who is depending on life support equipment to stay alive in your truck bed, the duals are totally unnecessary, inefficient overkill and complication..
If you can't get by with 130 amps, especially when most trailers now use LED lighting, something's wrong.

Dual alternators - to be able to run a 3KW inverter.
