Hi Bruce,
Yes, you can swap out the converter section of your # PD4575K18LS8 with 90 amp # PD4590CSV, but you will also need to increase the wire gauge of the cables running to the battery to 3AWG to handle the increased amperage.

Hey Bruce, how did the upgrade to the 90-amp converter go with your Montana’s control panel? Did the heavier 3 AWG wiring handle the extra load well? Your update could make it easier for others planning the same swap.
