Since my batteries are up front too, what about installing an inverter (2200w) near the batteries and wiring to a 50a plug and when I use the inverter, just plug it in to the front.  10-2 SOOW, and wire hot to L1 & L2?  
First, SJOW is adequate (SOOW is for over 600V).
Second, I don't understand wiring L1 to L2.  That sounds like a dead short to me !
Personally, I would purchase a inverter/charger/automatic transfer switch.  You can delete your converter.  The inverter will only over ONE leg of the 50A 240V power source so choose wisely.
