I am quite surprised you got that much charging done from your TV !
TV charging systems are optimized to charge ONE non-deep discharge battery. There are many assumptions made by the charging system about the this type of battery and its location.
NOT a truck and trailer
he has a Class C RV, also NOT the cheapest one,
his complete battery and charging system except maybe the alternator
has seen serious upgrades in wiring and capacity
but he runs an almost total electric house hold
and i think he needs to run his generator when he stops, before turning for the night
let his magnum inverter charger pump his batteries up
time for me to turn in..the warm pre-heated bed "electric blanket" is calling me
