To change your trailer from 30 amp service to 50 amp service you'll have to swap out a few components. Starting with the power coming into the trailer you'll need a new 50 amp power inlet like the Furrion Replacement Power Inlet # 381660. From there you'll most likely need to upgrade the gauge of your wiring running to your power center location to be able to handle the higher load.

Next you'll need a power center that's rated for 50 amp service, but you'll want to see the maximum amount of charging amperage that your batteries can handle, which will typically be listed on them or can be verified with the manufacturer. The # PD4590K18LS8 you were looking at has a 90 amp converter output, which is typically well above what most battery banks can handle so it would be a bit overkill. You would most likely be better off with a the 60 amp version # PD4560K18LS8.

As you pull each wire from your current panel you'll want to label its function to make it easier to label everything in the new power center. You'll obviously want to ensure that the power to the trailer is completely disconnected before replacing any components, including your trailer's battery bank. You'll also need to swap out your power cord to one rated for 50 amps like part # F5OR30SBOEM. There will be instructions included with the power center to will help walk you through the installation as well.
