A true deep cycle battery will provide considerably more discharge/charge cycles then the standard OEM marine/RV deep cycle battery, and a standard battery doesn't like being subject to a deep discharge...., compromises battery life.
Also, a shallower average DoD (Depth of Discahrge) will increase battery life. A deep cycle battery with an average 50% DoD will last at least twice as long as an 80% DoD. A typical GC-2 deep cycle battery will average 225 cycles at 80% DoD, but will increase to 750 cycles at 50% DoD

The newer OEM 3 & 4 stage converter/chargers supplied by Jayco do a good job of charging the battery compared to the older 2-stage converter/chargers. I installed an updated 4-stage converter/charger in my TT, but found that I can charge my (2) deep cycle batteries faster with my Black & Decker 40amp VEC1093DBD battery charger faster with it connected directly to the batteries. But, in my case the batteries are located at the front of the TT and the converter/charger is located 30ft to the rear of the TT.

I do not disconnect my battery connections from the TT when I'm charging with my Black & Decker charger. However, I don't have my TT shore power connected to my genny while using the genny to power the Black & Decker charger.
