POSSIBLE FUTURE MOD - DC to DC Battery Charging (Truck to RV)
As alluded to a few posts back, I am consider as a possible future modification, the addition of a DC to DC converter that can be used with the High Current Charge DC Power Outlet that I DO plan to add to the new truck.
Redarc, an Australian company makes a HD DC-DC Converter that can provide a 40 Amp charge output (depending on input current) - to the RV battery bank. The Redarc BCDC1240D has configurable charge profiles, including one for LiFePO4 batteries like the 4 I'm planning to have in the RV.
A few US retailers sell this. Here's a link to it on eTrailer - $430.
Here's an image of the Redarc BCDC1240D:

I've attached the manual for this product for anyone interested. Note that a 40 amp output unit is the largest they make. The 40 amp model only comes as a dual-input unit. The second input is designed for Solar. I would not use that input in my configuration. Any solar I may have will be connected to a Victron MPPT charge controller and then to the DC buss.
This device would be mounted somewhere close to the batteries. The space (likely under the bed or outside on the a-frame) will require additional venting to pull out generated heat and ensure the highest output current.
The power feed into this unit would be provided by an umbilical that I would create and terminate on the A-frame hitch into an Anderson SB175 connector housed inside a Trailer Vision housing with hinged door.
Then actual truck power would connect to the RV via another umbilical that I would create, also with Anderson SB175 connectors. One end would plug into the SB175 on the A-frame and the other end would plug into the SB175 under the truck bumper.
A Great idea to obtain proper charge profile despite the loss of stock charge circuit. Thanks Jim
