I have no dog in this. That's the only way that I would charge same as hooking the batteries up 1) with one battery you hook pos to trailer and neg. to ground. In parallel you hook pos to pos neg from the first bat to the second battery then from the second battery you go to ground. You charge the same way. That is the way I do it and will keep doing it. My batteries are 4 years old cheapo interstate. Had the 30 amp off for 48 hrs this week and the meter at my panel read 12.7. Gees must be doing something right. I also have a load meter, put that on and tested after 48 it show green, bought it at harbour freight. This is my opinion on how to charge my batteries hooked in parallel

I use a battery tender while my Georgetown is in storage (2 12 V batteries). And I hook the positive to the front battery and the negative to the rear most connection. Works great.

On my unit, a 2005, I must not have a very smart on board charger because I boiled my old batteries dry in just a few days. Ended up shortening their life. Now use the battery tender on the newer ones.

When I go to Florida in the winter, I leave my van in the storage unit with the battery tender to keep that battery alive until I return.

I also put a battery tender on the battery on my golf cart over the winter.

I am a big fan of battery tenders.

Speaking of batteries, my 2014 Georgetown has two coach batteries (can't insert picture right now). I am trying to determine if they are sealed, maintenance-free or is there a way to open and check the water level. Anyone?

This is actually the correct way to hook up to multiple batteries in parallel.

This is what I do. Why make it more complicated?
