Do you have a gen? What size charger? Magnum charger/inverter? 140Ah battery is on the small size as 230Ah flooded is the basic standard size. What make/model?
Recommend you spend some time boon docking like you expect in AZ before traveling. Even better if power is available and you can plug in if needed.
Consider installing a battery monitor so that you can determine your loads and (or reduce them) plus charging. Better ones are $200 but there are posts on very workable $40 variety on this board.
My first solar purchase was a battery monitor about 9 months before solar purchase. A battery monitor takes the guess work out of a energy audit which is recommended for understanding boon docking power usage.
