Question:
Do you guys have any idea if this would be a good upgrade in place of the older Magnetek 6620 power converter?

That ones a bit overpowered Chance! I recommend the WFCO Auto Detect RV Converter and AC/DC Distribution Panel item # WF96FR. This is 35-amp distribution panel with a lithium compatible converter. It will be rated a little higher than what you currently have, but it will still work with your current setup.
The Progressive Dynamics 4000 Series RV Converter w/ Charge Wizard and AC/DC Distribution Panel item # PD4060K, you were looking at is a 60 amp converter. Your Magnetek 6620 power converter is a 30 amp. You could also install the 45 amp Progressive Dynamics 4000 Series Mini RV Converter item # PD4045KA but I recommend going with the WFCO item # WF96FR instead unless you want to upgrade your wiring.
The WFCO item # WF96FR measures 11-7/8" wide x 5-5/16" long x 8-1/4" tall.
What kind of trailer or motorhome do you have?

Hey Chance, how did things go with the WFCO converter upgrade for your setup? Did the 35-amp panel end up being a good fit with your existing wiring? Your update could make it easier for others replacing an older Magnetek unit.
