Working on a plan to upgrade inverter, batteries, etc. So I'm better set up for boondocking. In my 2019 BS 3414.
I have an Elect engineer helping me with equipment, so I think I have that covered. Victron 3000w, LifePo batts, shunt, solar, etc.
My question is about location. It seems that I have room to put batteries, inverter and other stuff in the back bay where my plug and transfer switch is located. Assuming everything fits, is there anything I'm missing here?
Thanks

Tell us what you are replacing.. and you can list it here in classified free I believe and recoup some of your investment.. I have no inverter and will need one to take my daughter out to see the redwoods.. she has terminal brain cancer.. post tumor surgery and she is stable now.. after many rounds of chemo and rad.. but in the future.. just thinking if things go south.. then can use an inverter to power medical equipment.. does not have to be too big.. probably need cables and better batteries.. no hand out accepted please.. I will pay.. just a suggestion for you to list here..
Good luck and keep us posted

I have a 2014 Canyon Star 3956. Installed 2 Battlborn GC3 batteries, Multiplus 2, BMV 712 in the rear bay. I also installed the BIM for Lithium in the box with the BIRD. The only issue you might have is the generator. The Multiplus will only go into pass thru for L1 and L2 if L1 and L2 are 180° out of phase with each other. The Onan has both lines in phase with each other. I have lots of info on my install and a work around for the generator. My whole RV is now powered thru my multiplus. I can fun 1 A/C without the gen if needed and sometimes I do this an hour or 2 before I get to the next park. Oh, I also put in Soft starts.
Yes this is the same bay the power cord and transfer switch is in. Power cord and transfer switch are on the driver's side and the previous pics were on the passenger side. Here is a pic taken from the passenger side, if you follow the wires on the ceiling of the bay they come from the transfer switch to the multiplus. I am also attaching a document I made to explain the generator issue. I am also attaching my wiring diagram of my system.

Might be tight but you might be able to put the batteries in the pass thru and the inverter hanging on the wall to the left. I would take some cardboard and cut out a template to test fitment. Remember the inverter need room to breathe, about 4 inches on each side, top and bottom. Here are pics of where the BIRD is located. I know on my coach, I had 6 batteries, 4 on a slide out tray and 2 under the hood.

Think about all of that weight hanging at the far aft end of your rear axle, Tony! Batteries, in particular, are going to 'cost' a lot, in terms of weight, and will make the front end/steering axle lighter in the process. Not sure if you're on a 24k# chassis, but if so, check your current axle weights and then factor in your mods to see if you're still within limits when fully loaded (typical fuel, water, and 'stuff' included). I don't know of any minimum stated for the steering axle, but too light a load will cause all kinds of steering/stability issues going down the road and will be exaggerated with cross-winds from passing rigs or just plain windy weather.
Hope it all works out for you!

I had a similar issue and added the Victron Autotransformer to basically take the 2 parallel outputs from my Onan QD7500 which are not out of phase and it will take the 2 lines and make them 180* out of phase so my Victron inverter(s) (2 in my case) see the input pretty much the same way to sees a 50A shore connection. The autotransformer is installed between the generator and the transfer switch.
In my case it was so both inverters would charge when running the generator (280A @12V) so it charges those suckers up pretty fast

I’d like to hear how you dealt with the gen issue.

Do you have any pictures of this. I have just jumped the two at the ATS for now. Have a single multiplus 2 3000 with 4 200ah lithiums. And haven’t got it all dialed in quiet yet. Just looking for best option to make this work as it should. The jumper was able to run both AC’s, fridge and microwave before pulling off battery power. And have an 8000qd. Still feel like the 8000 should about be able to
Keep up.
Appreciate all of the information here. Thank you!
