I plan on full-timing, so I went with the big one, just in case. The price difference was minimal.

See my post above,
what model do you have?
45 amps DC is not overkill you will need it to charge your battery bank
-------------------------------------------------------------------------------------------
120 Volt side of things
You will have a distribution panel(fuse box) for your 30amp 120 coming into the bus (similar to the house)
so your main breaker will be a 30 amp 120 breaker coming in and you will branch out with other circuits from the fuse box,these will have smaller breakers on them say 20 amp.
---------------------------------------------------------------------------------------------------------------
Now on the 12 V side the "input" into the 12V Fuse box will be your batteries,and the output will go to your 12v accesories
just like in the car or bus.
You will need to charge these batteries or they will just be dead.
You need to replace the energy used somehow, altenators will do this while the vehicle is running...using up to the rated output of the alt(close to it)
Now with the vehicle off you will not have any way to charge the battery bank and the batteries will die.....the converter/charger that I posted will supply the 12+ needed to charge the batteries and alittle more so the 12v can be used and charge the batteries...so 45amps is not over kill.
When you plug in the 30 amp 120V shore power it will feed you 120V fuse box and supply the branch ciurcuts...one of which will be the converter/charger(so it has 120V to convert into the 12v DC) and thus your batteries will charge when plugged into 120V
Any questions?I will try to explain.
Just confusing.
SO WHAT PD DO YOU HAVE?
