Not sure where to post this question, but in researching additions of more batteries for boondocking, I think I could put two GPL-27T's under the rear dinette seat (unscrewing the seat panel) which I think would place them over the axle. The other two GPL-27T's go into the existing batt box. This would minimize the tongue weight or at least keep it down.
I'm guessing the heavier side of the 20'FC would be the curb side, with the door, wardrobe, refer, stove and cabinets.
What do you guys think? Is the street side lighter? Have a recommendation for cable gauge running about 8' to the front?
Thanks and Happy New Year!
