Alt size may depend more on if you have to recharge in the amount of time you will be driving. If I was going to stay for days somewhere I would still want to have a separate start battery from house. I have a 250 alt and single start battery. I just charge it with charger and shore power or an inverter on the start battery when driving. My 100ah house battery charges stuff, runs lights, fans and other low draw things. I opt to stay where there is power when I need cooling mostly. Unless you build a huge system you can not really power AC/heat from house battery over night. I find the real power hogs to be AC and Heat. How much power will you be drawing out and over what period of time? Will you always be driving the next day to recharge? Will you only have the b2b charging or will you have shore power sometimes. Seems to me you have more questions to answer before you can make a good choice. What have other people learned and what choices did you make with regards to charging systems?

And then maybe install a single 60 amp b-to-b charger with an allowance for a second if it seems necessary later. At this point I am thinking the best choice would be the single 250 alternator, dual starting battery, and also get the factory battery guard option. So this is what I have discovered in trying to figure out which battery/charging option to order. And it would be possible to hook up more than one and run them in parallel. But 60 amps is actually quite a bit of juice - about 750 watts. One drawback to the b-to-b chargers is their relatively low current ratings (60 amp is the highest I have seen). This means that by using one of these b-to-b chargers, the Transit AGM battery (and charging system) can be used to properly charge LiFePO4 batteries. All batteries have published specifications for charging (how much voltage, for how long) and with these battery to battery chargers you can set them to match whatever batteries you are charging. The important part is that the two batteries can be different types because the user has control over the charge settings. Example The idea is simple, just connect the batteries together using this device, and then you can use one battery to charge the other. In trying to solve these problems, I ran across a product that I wasn't familiar with: a battery-to-battery charger. This might not be quite as bad as it sounds, but it certainly isn't ideal. So if I were to connect my lithium batteries to the Transit charging system the batteries would be charged at the wrong voltage and the wrong rate. They need to taper the current as the battery charges.

Lithium batteries can accept large currents almost all the way to full charge. Also the charging profiles are significantly different for the two different battery types. The stock Transit charging system seems ill suited for charging lithium batteries because AGM batteries use a significantly lower charging voltage. I am using LiFePO4 type lithium batteries because they save so much in weight and volume, and they charge much faster.

At least I think that's how it would work.Д«ut I am not going to use AGM batteries. The PGM would prioritize the vehicle loads and the camper battery could have what's left. In that case I could tie directly to the PGM and get up to 200 amps charge out of either the single or dual alternator setup. This setup would work well if my camper battery was going to be an AGM type battery. In addition, I know that there is an option for a Programmable Battery Guard (PGM).
