We are getting close to firing off the system, today Kathleen and I pulled two 4 wire 6 gauge cables from the bay just behind the mid door to just behind the tag axle drivers side, I originally had planed to put the new inverter where the old inverter was located but with the big slide for cargo there I moved it up one bay. Pulling those wires WAS NOT EASY, after running a fish tape through both the 3" pieces of conduit and pulling rope through from where the old inverter was to just behind the drivers side tag axle we decided we need some help so Kathleen when to the grocery store and bought a big bottle of vegetable oil and a can of Crisco. I measure the length of the conduit and cut some 1/4 tubing 2 foot longer than the conduit drilled 6 small holes at different angles on the tubing and put a screw in the end of it then used my old fire extinguisher bottle to pressurize the corn oil then shoved the 1/4 tube down the 3" PVC and had her open the valve while I pulled the tubing out slow enough to coat the inside of the PVC with corn oil. After that was done she got between the tag axle and the drive axle and pulled the rope while I applied the Cisco to the cable and it went very smoothly. We destroyed our work clothes with all the road grime from brake dust that built up on top of the transmission cooler and the pressure tanks where both cables went.

Now the entire coach will be going though the inverter 100% of the time this eliminates the need for a surge protector as the inverter acts as a non interruptible power supply. When I was removing the old inverter I had a flash thought of doing what Newell did with a bypass so that in the case of a problem I can still run off shore power or generator.  We will have two 50a 220 receptacles on the wall that the inverter is mounted, if we need we can unplug the inverter and put a jumper between the in and out of the inverter.
My connections to tie the inverter into the coach will be at the transfer switch after seeing the routing of the wires to the main electrical panel I will not be using the buddy plug wiring or hole and leave alone. The inverter alone weighs 148 lbs, the panel I mounted it to had plywood and thank God metal behind it so I used self tapping screws to secure it there. 

The 500ah of 12vdc coach batteries has been isolated from the 250ah 48vdc inverter batteries, both still use the same cut off switches just one is identified as coach and the other inverter. I did noticed a big DC shunt in the battery compartment but not aware of a amp meter, any thoughts there? The 48vdc has a bluetooth DC shunt and the inverter is wifi so we can see what is going on system wise. All the battery connections cable have been wire brushed and cleaned.

I will have a bluetooth MPPT solar charger coming off the 48vdc system that is charged by the inverter and will supply the charge to the 12vdc coach system then will eventually add a 110vac 48vdc forklift charger just in case there is only 110vac. But thats on the back burner now.
