Depends on how the current RV batteries are charged.
If they are charged directly from the RV alternator, then yes, you will need a DC-DC charger (unless your alternator is able to change charging profiles). The biggest concern is that the lithium batteries can draw a ton of amps when charging and abruptly shut off when full... This can burn out regular alternators.
If you have an intermediate charger (mine does) you could likely use that, even if it doesn't have a lithium profile. It will simply charge these to about 80-90% full. Even at 80% full, these will have almost double the usable capacity of a single 100Ah deep cycle
I just replaced my travel trailer batteries with lifepo4. I disconnected the the tow vehicle 12v/alternator charge wire from these batteries. My lithium batteries only now charge from the dedicated charge controller when connected to shore power. I then added a tiny 4ah sealed battery that takes care of my emergency breakeaway trailer brakes, which is only charged from the tow vehicle.
This was the cheapest solution I could come up with. In your scenario, the question to ask is whether you need alternator charging or not. In my scenario, I did not need to charge batteries going down the road, but I did need to ensure the emergency breakeaway brakes would still function (hence the 4ah battery, only connected to the breakeaway switch and the tow vehicle 12v power for charging).
In my research, a new DC to DC charge controller was too expensive of an upgrade for my old trailer.
Need DC to DC charger, most lithium needs a different voltage profile. Victron, renogy, ecoflow, ect make em. I would tax your alternator too much though. I like the Victron personally.

May grab another one to hook up to my River 3 Plus (or maybe hook them together to do a 24v battery).
I have a cheapie 2 amp LiFePo4 charger that keeps it topped up and use an XT60i cable to charge the Ecoflow. I have a 10 amp charger if I use a lot of the capacity and need to recharge it quicker.
Even having to buy a separate charger and connections, a heck of a lot cheaper than buying an extra Ecoflow battery. Sure I loose some of the convivence of the branded battery unit, but for the price, I have no issue with it.

That's what the discussion about dc-dc chargers is about.
Connecting batteries of different chemistries in parallel is generally not recommended and most likely a bad idea.
Great deal though.
As long as you treat it like other batteries (with common sense) LiFePO4 batteries are very safe.
