I respectfully disagree. It totally depends on the power
center in your RV. Some/many? are 3 stage and do a fine
job on their own. My last trailer was 4 years old when I
traded it and the original battery was still going strong.
Also Bente mentioned something about the car charging
it on the way to the CG. NOT gonna happen.
Due to the distance and voltage loss between the engine
alternator/voltage regulator and the battery in the trailer,
it will likely not receive much of a charge while driving.
Finally, Bente, be careful. A discharged battery can freeze
and break in the winter. It's also bad for a battery to
be stored in a discharged state. You don't mention where
you store your trailer but you need to consider either
making sure it's charged B4 you store it or plug it in
when you get home or to the storage facility.
If none of these are possible you might need to remove
it and take it home when the trailer is in storage.
In that case I highly recommend a battery tender charger.
Just google battery tender. Amazon.com has them as
well as some automotive parts stores.
