Hey Sam, I looked up your 9856 wfco and since it is rated at 55 amps yes you could upgrade to a 60 amp setup like the Progressive Dynamics part # PD4060K that you referenced and you'd be fine. Normally if you go with a lot higher rated converter you have to also upgrade the wiring but since you are already really close to 55 amps you are fine.

Hey Sam, how did the upgrade to the 60-amp Progressive Dynamics converter go with your RV setup? Did it handle your pair of 6-volt batteries the way you expected? Your update could make it easier for the next person looking at a similar upgrade.
