Ordering a new 2500 diesel to tow my 36 ft 5th wheel. I have options to replace
original alternator with a 220 amp, 2 220 amps for 440 amps or add 1 220 amp
for 380 amps.
What should I do? I have no clue why the choices and can't get answers.
My question now is why? What is the benifit? Why not 440 amp? Not being an ass..lol. I really don't know. Thanks for your answers and time.
The only thing I can see is the recharge capability and speed of charging going to the 5th wheel. Do they wire the second alternator strictly for the 5th wheel? Do you know if they are using massive diode protection to prevent feedback from both alternators.
I have no idea yet. No one could even tell me if I would need them or not. They just have no clue at the dealers.
I would just go with the single 220 amp alternator, that should be enough for the 2 batteries in the truck and 2 batteries in the RV, unless you have went with some massive voltage storage in the RV.
Also remember RV batteries are usually deep cycle you don't want to cook them on fast charges.. Fast charging them shortens there life and you won't get full deep cycle out of them.. Slow is good. Lower amps
Thanks all. I will go with the 220 amp alternator.
The 7 way plug is usually limited to about 10-15A, so that is the max the 5th wheel can get.
