Schumacher is well know in chargers.
I have 2 of theirs computerized chargers and 25amp charge is really good.
The other is also 75 amp starting booster and is loud, so test the noise before buying.
But before crossing off your camper converter, check what exactly it is.
For 2016 I would expect decent one.
The 40 amp converter in my 2004 camper will not support jacks, while 30 amp truck wire will, but I monitor voltage during charging and even it goes too high on long storage, I does decent job on standard recharging.
