Whole RV Inverter/Charger

NO thats not back feeding
those are out put breakers going to the sub panel

NO. Those are the feeds INTO the panel. That's why the screw is there. Check your NEC 408.36d. The screw wouldn't be there if those were output circuits

back feeding is when you bring hot "power in" from what is leagally and output circuit

Yep, just like the breaker panel on my RV.

take a double ended suicide cord
plug end 'B' into an outlet in the RV
plug end 'A' into a shore outlet

THAT IS BACK FEEDING

I guess that's back feeding, but it's a pretty contrived way to do it and that's not really analogous to what we're talking about here.

Im not saying that backfeeding is a bad thing, just trying to describe it to give a visual before I could post pictures. It has obviously caused more harm than good with you.

so the guy at fleetwood, messed up
and you re-balanced it..good
i never said not to re-balance
i said don't put all the heavy items on one leg
i would separate the (2) A/C they are the two big items most likely to be on for hours at a time thw other loads are more intermittent, this keeps the neutral leg from being overloaded by an imbalance
rearrange the other loads
having an a/c on the inverter leg won't hurt
you won't be running the a/c with out the genny or shore, not near as likely to forget as say the WH or fridge
tv, outlets, ceiling fan, MW, IMO must have for inverter
A/C can be on that circuit and the washer/fireplace IF you want, the victron pass thru will handle it when using genny or shore power and those are items not likely to be accidentally left on, or come on automatically (victron is an excellent choice)

and unless you have a Manual lock out breaker switch arrangement for generator and shore choice, there is a 50 amp 3pole TS someplace, mine is a big silver box in the electric bay, because my breakers are in the cabinet over the BED

I see now that we have some confusion. First of all, I don't have 2 ac units, only one. Hell, for all I know, the AC2 circuit is a spare. I figured they split it across two breakers to use smaller breakers. And yes, I only use it with the generators.

Also, I do NOT have an on board generator. I use two Yamaha suitcases. So, currently, the only way to get AC power into the trailer is through the shore power receptacle on the side. So to say that I MUST have a transfer switch somewhere is erroneous, I believe.

yes in some respect
but 30amp RV don't come with electric heat fireplace and washer dryers
and the (2) a/c only run on generator, RV is usually setup that only (1) a/c can be run on shore power, then its power management time for MW etc..
its not all run at the same time when the RV has 30amp main

But I doubt the engineers designing all this were playing a game of Russian roulette, betting on what you will and won't run at the same time. I can't run the fireplace and WD at the same time, they are wired to a toggle switch so it's one or the other. And again, only 1 AC unit.

I guess what I was trying to say is I think load balancing is less of a concern than you are making it out to be because there is nothing a 30A 120v service can do that a 50A 240v service can't do, even on one leg.

Can I run my entire camper at the same time from 1 leg if I put it all on one leg? Don't know. But I can guarantee you that if I can't with my setup, there's no way you can with your 30A 120V setup. There is, however, the possibility that I can and the 30A setup can't. That's all I'm saying.
