I was looking over the standard features that are listed with the 2009 Pumas and noticed that Lester chargers were listed . Is the Lester mounted in the bilge or is a external charger that has to be plugged into a outlet on the hull . Im a big fan of the dual pro brand of charger . I have a four bank Dual pro in my 2005 Puma . Would it be possible to order a new boat with a 4 bank dual pro charger ?
