majestic 28a
Has anyone added a 2nd house battery to a Majestic 28A? Have some ideas about how to do it but would love some more ideas.

Yeah I did.
I have a 23a tho.
So on mine there is the battery outside under the coach. the rest of the rats nest of wiring plumbing, electrical boxes are under the corner bed.
Under the corner bed is isolator blocks that bring in the power from the outside battery. then finish into the convertor/charger. there was enough room to put in another battery and bring in all the solar parts and now have 2 batteries with 300ah capacity.
1 is not enough for anything off grid. adding the 2 gives me near unlimited power except for winter camping along with solar is my absolute top favorite mod for the rv.
I would suggest locating the convertor/charger which can be under a dinette on some of these and find the isolator blocks you can then tap into it to add as many batteries as you have space for.
even better then what i did would be bring them all inside. i have temp compensation on the one inside but not the outside one. Both are AGM's and have really improved the boondocking capabilities of this super basic rental machine.
Also IMPORTANT only agms,lithium are allowed inside the rv. SLA's are not for inside unless you want an elaborate sealed vented battery box that you won't have room for and holes in the side of your rv.
I like the other post on the extended tray system you could easily go this route as well. probably less hassle in the long run. This route tho might have voltage drop unless upgrading to welding cable coming into the rv. they use pretty silly wiring coming in. like 8 gauge or 10 i forgot. I put in 00 gauge for solar, less dc voltage drop.
