new member looking for help

110 TO 12V CONVERTER (factory installed and operational)
12 TO 110 1800 WATT INVERTER (not currently installed)
1 ½ AMP FLOATING TRICKLE CHARGER (add on, installed and apparently working)
12V DC BATTERIES (THREE) – TWO UNDER THE HOOD, ONE IN THE CAMPER (under the hood installed and operational third battery to be added inside the camper in the spring)
SOLAR PANEL (near future add on)
SOLAR CONTROLLER (near future add on)
110 V/BOTTLE GAS FRIDGE (installed and operational)
750 WATT MICROWAVE (installed and operational only when connected to AC input)
12 V LIGHTING (TOTAL OF 5 1157 BULBS) (installed, functional for 1 to 5 selectively)
SINGLE BREAKER DISTRIBUTION BOX (ONE 20 AMP BREAKER) factory installed and functional
The two batteries under the hood can be split so as to not discharge the vehicle’s operating battery. 0ga cables are run from the secondary battery to the camper (not yet connected to anything). Plug in on the side of the camper for 110v AC power that connects directly to the breaker box then to to the converter. Convert has a switch labeled AC in one direction and DIR in the other. AC of course lets everything in the camper operate off the converter while connected to shore power. When switched to DIR mode only the lighting (DC of course) runs and there is no AC. The DC from this converter is supplied through 14 gauge wiring directly into the walls of the camper and as near as I can figure only to the lights. I have discovered what appears to be an “add on” trickle charger in the camper that has been tapped into the dc wiring again through 14 gauge wire. The trickle charger (ac operation) lights up indicating it is feeding a charge to the vehicle’s batteries to charge it (them unless split). I do have 10gauge wires supplying nominal power to the camper from the truck’s batteries which is currently used only for the interior lights.
From what I can see, AC power is distributed from the breaker box to one circuit consisting of three dual plugs and to the refrigerator and micro-wave. Two sets of DC wires run out of the convertor directly into the wall, but two red and two black wires come out. I think (through some testing) they run to the three ceiling mounted lights. I have not found any dc power from the converter to the batteries (either in the camper or the truck) but at some point I’d like to add the capability to charge the batteries from this source when connected to shore power.
I’m trying to configure this to be “idiot proof” so if my Grandkids or someone else uses it they can’t destroy anything. I need to somehow wire all this together through one switch to work on either AC or DC without cross connecting or shorting anything out.
Can anybody figure this mess out with/for me?? I want/need for my ac circuits to function when I’m hooked up to shore power, but also want them functional if I’m only running off battery power. How do I keep from feeding power back??? Where do I connect the various components etc. I may be reading more into this than is needed, but I tend to be somewhat paranoid when it comes to electricity anyhow and I certainly don’t want to destroy my pickup while configuring/operating any of this.

I'm also looking into installing an HHO system on my truck to try to help better fuel mileage (which is currently non-existant). Any suggestions on how to help mileage out cheaply. Not a lot of available funds here. it's a 1996 ford f250 4wd with a 351 windsor engine, overdrive transmission.

Hi Carrowor -

Have you tried any RV type forums? I expect you'll have better luck there.
Project MPGiata! Mods for getting 50+ MPG from a 1990 Miata
Honda mods: Ecomodding my $800 Honda Fit 5-speed beater
Mitsu mods: 70 MPG in my ecomodded, dirt cheap, 3-cylinder Mirage.
Ecodriving test: Manual vs. automatic transmission MPG showdown

has launched a forum for the efficient new Mitsubishi Mirage

I wont pretend to know how to start tackling your mess there, but I do know Battery Isolators help keep systems from discharging all batteries, therefore prevent current drain going back. That might help you with your AC/DC issue.

Thats as far as I go .. LOL
