Victron is pricey, but it top of the line and rated for marine use. They will hold up in an RV.
The half ass answer is that you could probably toss this right in in place of of the lead acid battery, as long as you remember a few things.
This will likely not fully charge on a system designed for lead acid, as other people have said, proper voltage for a fully charged lithium battery is close to 13.4v, lead acid is closer to 12.6. That being said, lithium batteries do not like sitting fully charged for long periods of time and even at 13.6v this will give you more useable power than 300 AH of lead acid batteries. One caveat is that you cannot charge lithium below freezing, it can damage them. This is supposed to have a low temp cutoff for charging, but in cheap batteries like this, I'd take that claim with a grain of salt and wouldn't rely on it.
A good DC-DC charger will have a low temp cutoff that works.
Another thing to consider is the BMS charging lithium directly from an alternator not designed for it will put stress on the alternator- lithium batteries can suck up a lot more energy than lead acid when charging and can overheat alternators, and they also shut off charging immediately when full, this also can damage alternators (that are not designed for it).
All in all, this with a soldier DC-DC charger is the safest way to go. You will get the most out of the battery and protect your motorhome's critical systems (battery and alternator).
If you want to get fancy, you could tie in solar as well. I use a renogy solar MPPT/DC-DC charger on my sailboat that uses both the motor and the solar panels to charge both the house and starting batteries. Victron does not make a combo unit, they prefer to keep those functions independent.

The sudden current draw of a fridge can kill a standard apc.
