Hey Dean, welcome back! Really you only need to change the batteries and make sure you have a converter that has a lithium battery profile and that's really it. If you let me know what the amp rating is of your current setup I can match it to a lithium compatible option if what you have doesn't have a lithium profile.
For example, the Progressive Dynamics panel part # PD4045KA that you referenced has a lithium profile on it and would work well. It is rated for 45 amps too.

Dean, I have the progressive dynamics converter. I installed it in a 30year old truck camper. In your situation where the converter is a lot newer, there probably is an available kit, that just swaps out or adapts the charger portion of your converter. Much less work and expense than a total swap out. My guess that you have a WFCO 30 amp converter. Get the converter model# and reserch wether you can adapt your current unit to a lithium profile. Another thing to think about, your current converter will charge the lithium battery to about 75-80%. The lithium battery BMS will control the charge. If you plan on having solar charging the solar unit could potentially top off the battery. I ran like this for a few years on a Lance travel trailer. We had plenty of sun when boondocking camping.

Unit works well and has a switch so it can accept lead acid or lithium battery'. I suggest you contract an RV tech to help with change over as unit does not come with any installation instruction or schematics. Wires have NO identification and are so short have some butt connector and additional wire on hand if you need to slide it into a tight space and do not have top access. Lastly This unit is smaller than probably what you are replacing. You will need to reframe it in. Id it is floor mounted add a piece of 1/2 " plywood in case of water leaks. Do not use OSB or Press board.
