Yes some fatter wiring would be better for the long ways between the front and middle of the MH. This test shows how it is now. Gives me a "baseline" for any improvements.
I was surprised revving did not make the amps go up any. Actually went down a bit compared with idling. I thought alternator voltage would drop to 13.8ish fairly quickly, but nope.
Huge PITA to improve that wiring any more than done already at the easy access parts, so have to decide if the extra amps would be worth it for any scenario that has alternator charging being important.
Not at all clear that getting say 35 amps is any better than 25 amps for an hour of idling. 10AH is peanuts.
Another thing with way higher amps is whether the battery bank would even be low enough to accept that many. Depends on the scenario, and how many times a year for each scenario when calculating "worth it".
