Two Questions for a Potential New Tow Vehicle

When I had our current tow vehicle built I ordered Dual 150amp alternators. We are thinking about a new tow vehicle and I have the option for the same dual alternators of 1 250amp alternator. Which is better for 5th wheeling and why?

Also I have the option of having the truck built with a 20k or 24k Curt Hitch already installed at delivery. Anyone have any experience with the Curt 5th wheel hitches?

Merry Christmas

    A single H/O alternator should be fine. Have a stock alternator & 2 group 24 batterys in the truck.

    My boat has a single H/O alternator which charged a total of 5 group 31 gel cell batterys arranged in 3 banks switchable to any combination I chose. It worked hard since all of our overnighting was done on the hook & we seldom had more than 1 1/2 hours of run time to recharge.

    FACTS measured amps on my rig:

    My running lights LED ..........1 amp rounded up
    Brakes ........................12 amps rounded up and short duration, absorbed by batteries
    Charging not measure variable 20 amps max
    also, single battery...since I have a gas engine.

    so total 33 amps....no way I need more than the standard 157 amp alternator
