Power Service Distribution Panel Replacments

[Apache Dave]

Thank you to all who have answered my post about converter issues. I have the WF 8930/50--50 amp Service Distribution system in my 33 ft 5th Wheeler. Which Progressive Dynamics system is a exchange/replacement? I want to upgrade the system but do not want to have to cut/remodel the wall where the existing distribution panel is. I have the WFCO 55 amp power converter as well - Model # 9855. What is the replacement converter unit for this? Or what system has all service and converter built together for a replacement/upgrade? Thanks, David
