2010 Flagstaff 228D built in battery charger?

[kharless]

Does anyone know if my 2010 Flagstaff 228D has a built in battery charger? If so, can I leave it plugged in while in storage to properly maintain the battery? Note: I am in Phoenix, Az so summer temps are high. The trailer is in the shade but it still gets very hot!

According to Forest River's web site,

That's for the 2011 models, but it's probably the same for the 2010's.

You can leave it plugged in but you need to check the batteries water level every couple of weeks or so.
