    I have a 2011 F-350 6.7 Dually 4x4 that tows an 18K 5th wheel. The truck now has 146k miles on it and I have never changed out the alternator. I am thinking of doing it as preventative maintenance next week. I have a stock alternator and would like to upgrade to a higher amperage unit. Any suggestions? If I get the OEM HD Alternator, is it plug and play? Same wiring harness, mounts, belt, and pulley?

    Also plan on changing both water pumps, hoses, glow plugs, idler and tensioner pulleys along with the belt. Any other suggestions on what to change? All components are original to the truck having lasted 146k miles thus far.

    I know if it is not broke don't fix it but we do a lot of boondocking (in the desert) and can't have the truck breajing down in the middle of nowhere when I can do things to prevent it.

    Thanks!

    John

    I changed the factory alternator at 165k miles, it was overcharging. You might check on the alternator that they use on ambulance or firetruck applications if you want a high output one.
