Adding additional batteries to the tongue area is not all that difficult. You are not restricted to the one battery box. What I did here was to pick-up some metal angle strips and bolted inside the original battery box angle iron strips which allowed me to extend several batteries over hang on the tongue area.
Others like shown below here have added maybe diamondplate lock up tool box that will house additional batteries and can be centerd on the trailer tongue. The 48-inch wide battery box shown here will hold 4EA Trojan T105 6V batteries (Two groups of 2EA 6V batteries connected in series that will produce a whooping 450AHs of battery capacity.) The battery position works best if it is located between the trailer front wall and the Propane tanks. The real limiting factor is the added weight you may be putting on the trailer tongue when connected to the tow vehicle.
