Vehicle: (2015) 2017 Majestic 19G

Problem: The coach battery only powers the 120v outlets when the RV is connected to shore power or when/if the generator is running.

Question: Does anyone know what would have to be done to have it so that I can utilize the coach's battery without being plugged in or having the generator running? If someone has a wiring diagram for this model, that would be great.


I am looking into adding a secondary battery bank; however, based on our power requirements I think I could get away with just tapping into the coach's battery for outlet power and recharging the battery when in motion (or using the generator). I do not need constant power from the coach battery, but I would like to tap into it without having to dump $500-750 in battery gear (or running the generator).

Trying to replace standard AGM battery (which is dead) with LiFePO4 battery on my CA Majestic 28A.

Anyone know the location of alternator diode/solenoid so I can simply disconnect it (or put in a current limiter or a switch)???

I looked at this and heard from multiple people (who I'm sure know more than I) to put a proper charge controller in. The LiFePO4s are expensive things to blow up by overcharging. I looked at it some more and decided to get the local shop to put one in as part of a solar install.

I have a solar charge controller installed already. But this it seems requires a DC-DC charge controller (another $200 or so). Just wondering if I can simply disconnect alternator to house battery charging mechanism for now.

I'm contemplating buying a Cruise America 23A Thor Majestic. Is the pricing pretty firm to the price listed on their website or did anyone on this form negotiate a better price with them? I see they are baseing their pricing on mileage mostly. Thanks!

1.Ok the cheapeast and easiet way is to buy an inverter. We brought a full sine wave 1000w inverter which was bigger than the power we intended to want, so as not to overload.
2. Fitted just above the main battery locker and used 2 cables the same size as the main battery cables to join battery to invertor. This required 2 drill holes in the floor.
3.Hole cut out in the panel next to the invertor for direct access to 110V and 12V oulet socket on inverter. The inverter had 2 x 110V socket.
4. As required we plugged into these outlets, including a short extension lead sometimes.
5. This means the system is totally seperate from your house 110V sockets and you never have to worry about the 2 systems shorting out.

We ran no problem from this using laptop, fans, keybpoard, charging phones etc whilst boondocking. Even at Lake Mead for 14 days in 100F in the summer.

USB sockets
1.Buy ones with 2.1A and 1A outlet on them (Amazon/ebay). make sure they have a mounting back plate as wellUSB socket
2. Remove a 12v light and pull through existing 12v light cable.
3.Join cables to this and then to the usb outlets you fit, having fed the cables back up the light hole to your USB outlet position.
4. Refit light.
5. Suggest also fitting on/off switch next to usb if they have a blue power LED light with them. This stops the glow at night and the small power consumption when in storage.
you will find lots of info in the Owners Essential RV Handbook on Amazon
