I think the existing wiring back to the house batts will limit the amps to the batts, but I don't know by how much, similar to a converter's amps on typical RV wiring to a battery too far away. This could negate some of the advantage of a higher amp alternator, but the wiring paths could be improved.
This MH does not have a built-in gen, so that means portable. Interesting to compare the cost of say a 1000w Honda with a 40amp charger, vs a new alternator that can do 40 amps instead of 24 with the MH sitting there idling, plus better wiring to the house.
How many amps can your battery bank accept? (Assuming you had sufficient wiring upgrades)
Many alternators have smaller pulleys that will spin the alternator at higher rpms while idling. As long as you don't overspeed it while running down the road.
We don't have these overspeed problems on diesels. My alternator is listed up to 6000 rpms, but the only time my Excursion would see 6k rpms was if it sprouted wings and flames were shooting out the back :E LOL!
