I did I got a 80 amp one. I have a 30 amp breaker on the line and so far it hasn’t tripped.
You can use that excess capacity to run other 12V accessories.
I do recommend connecting the buck converter after the battery disconnect switch. They draw a little bit of current even when you are not using them. You would not want it to drain your batteries when the truck sits unused for a time.
I should have seen this earlier...there's another option, albeit a bit pricey, for 24v to 12v conversion.
A battery equalizer...it's designed to center tap a dual battery ,24v bank, and safely regulate and charge both batterys.i used one for several years in my m1010 for 12v power. Mostly for the cab instruments, and headlamps/lighting. Used a lot in commercial coaches and larger RV's ,availible in many amperage ratings...Works very well, and never failed me, but I admit I didn't trust the electronic wizardry. Since you have Electric steering, this should not trouble you at all, lol.
The one I used was from Vanner ...the price these days is rather high. These things are expressly designed for what you want to do, but prepare for sticker shock...you might be able to score a used unit online,or at an rv shop...
I on purpose but a smaller breaker in to protect it an So far the the breaker hasn’t kicked out my steering, and now I’m in the process of rewiring the lights to 12 volt. Won’t be an issue for I’m never going to be caught out in the dark.
