It seems someone at Champion is misinformed. I'm pretty confident that they still read this thread (even though they are banned from posting here) so hopefully the employee in question will be brought up to speed.

That's way too low. Even the typical generic RV deep cycle/starting combo style battery tends to be around 85 AH. At a 1.25 amp charge rate you're looking at between 75 to 95
hours to charge it depending on the effeciency of the charger. Clearly running a generator for 3+ days straight to charge a severely depleted battery is not realistic.
At 1.25 amps, realistically, you're probably barely keeping up with the parasitic draw of just having the trailer plugged into the battery with the fridge on, CO2/Propane detectors, radios on standby, etc etc.
Most people purchase a standalone charger capable of at least 25 amps. Reportedly a single Champ 2000i will handle standalone chargers in the 50 amp range as well. It was great though when I only had a single standard battery, charging it from 50% in a matter of an hour or three.
I bought one of these at Costco:

At the full 25 Amp charge rate it only idles a single champ up to perhaps 40% throttle, so it's still relatively quiet. Even at 25 amps though it takes a good 6-8 hours of run time to fully charge my dual 6v golf cart batteries, so I'm looking for a 50 Amp model.
