I am actually thinking about making a carrier rack on top of the frame, but first, I thought I would ask you.
The question is: Have any of you ever upgraded your battery carrier?
3 batteries woohOOO!
You will be doing some boondocking!
You can build what ever you like as long as it is structurally sound.
2 points of concern:
Additional tongue weight.
It is always good to use the same type and rating of multiple batteries. If they are not they tend to "fight" each other during charging and discharge. Not sure how much of a loss of battery life that adds up to. But it could be significant. Maybe a EE will chime in.
And yes I am planning on adding a second battery, but using a disconnect switch. Which negates any battery differences.
