This is a multi-question post so bare with me.
1. I would like to add a battery box on the tongue of my 72. The 2 pics attached show a custom one on top of the tonque and a factory one that hangs under. I think the "ON" tongue would easier to do but then the question of the trailer plug comes in to play.(attached pic of trailer plug)
2. Where is the trailer plug on the newer trailers?
3. Since my shell is off and I'm rewiring anyway, would it be easy to move the trailer plug? or advisable?
4. Lastly (I think), I ultimately would like to upgrade to (4) batteries and solar(600 watt). The general concensus of the forum seems to be that (4) batteries on the tongue are too much weight. I've attached a floorplan of my proposed layout. I plan on putting the inverter, etc.. under the front seating area. I also understand the closer the batteries are to the inverter, the better. So, any suggestion from the forum for additional (2) battery locations, would be great.
