My Centurion CS2000 (8AMPS/20AMPS) seems to have gone out.  It will no longer charge the deep cycle battery when plugged in to shore power.  I am looking to replace it and believe I have narrowed it down to two converters; WFCO WF-8735 Series Power Center and Progressive Dynamics PD4135KV Inteli-Power Converter with Built-in Charge Wizard.  I am a complete novice so I am hoping to verify that these two units will work with my 2002 13' Scamp.  Also would like any feedback on either or both units.  I plan on taking the old one out and installing this one myself.  Thanks in advance.
