To answer one of the questions in this thread ... I installed 600AHs of LiFePO4s in my camper and had heard of concerns about them hurting the alternator.
Set up some test leads between the 7 pin connectors (truck and trailer) and measured draw with an amp clamp, with batteries discharged down to 60%(+-) as I recall.
At an idle, the most I saw come from the truck was 8A.
Certainly not any sort of overload condition.
Would it be higher with more RPMs? Never checked but conventional wisdom seems to be that the concern is more about configurations of on board alternators, like motorhomes and boats, whereas the wire size and distance on trucks, serves as a sort of self limiter.
9Kish towing miles, with no problems.
YMMV
