50A Tow Vehicle Charging!!

Got my tow vehicle charging finally operational.  I put a 2-conductor #4AWG "truck" plug on the front edge of the front platform.



I put a mating one on the back of the tow vehicle (with some selective cutting and finagling) under the trailer plug.  Used #4AWG cable from the truck battery with an 80A fuse all the way back to the plug.



Bought an oversized #4AWG "trucker" coil cable to use between.  I will make a lift-clip to attach to the small rod around the platform to give it some support mid-coil.  There's plenty of coil stretch (almost too much) for turning, etc.



Inside the camper is one of these going to the main battery bank via large bus-bar.  Will have a future post about the entire electrical system.



With the truck just at idle, I get 33A going into the batteries!  Should be able to use this while driving *AND* the 400W of solar  on the roof  (at the same time), while on the road, to quickly get the batteries back up.

    I did used a hole saw and drills to raise the female connection on my bumper too - but the use of coiled wire to bridge between the TV and the trailer is brilliant!
