It also appears there is an issue with the batteries charging when connected to the truck. Unit goes to the dealer & that is one more thing for them to check out.
4-5 hours sounds more realistic. I thought 2 12v 80ah batteries you would get closer to 8hours though. ..16 hours would kill the battery. I think I could get 16 hours from just my 2 T-105's but they would be well below the 50% rule after.
Don't expect too much from your trucks charging system. My SuperDuty has a high output alternator and it puts back 3amps to the trailer. That's not much.
