No problem, I just did it last summer. Remove the propane straps; cut bottom bracing to fit to edges of frame, and weld on moving the tank as close to the tongue as possible ( make sure you leave room for your jack crank); make bottom bracing for your
battery box, and weld on; pick a
battery box you like and make a frame out of small angle iron and weld together, then screw or weld to bottom bracing; attach your battery box to it with straps or screws and voila... Done. ( except wire hook up)
