There’s no such thing as “a little bit of damage”. Whatever you can see is just the tip of the iceberg. I’d imagine if you can see that much drop in the wall, the actual damage is much more widespread and will most likely go up into your roof. Damage to a structural support is something I wouldn’t want to try and deal with.
My suggestion is to see if you can get anything for it on a trade in for a new camper.
A little over the top dramatic, are we?
Damage can be widespread or local, no way of knowing what you have until you open up the can-o-worms.
Either damage can be fixed, it is more about how much time and money you are willing to toss in.
Chances are, OP simply needs to find and remove damaged material back to good studs in the floor and wall edges. Then it is the matter of bridging the repair areas by "sistering" new material in place and correcting the damaged metal frame part.
Takes time to do this but chances are if OP is handy with basic carpenter tools like circular saw, jig saw, nails and hammer and perhaps drill/screw gun they should be able to make at least a good enough repair to continue using the RV.
Telling one to sell or trade is pretty extreme without seeing in person and getting a good assessment of the damage.
Typical RV building techniques, the floor is built on the frame, the walls then sit on the flooring and the roof sits on the walls. A failure of the floor studs at the edges allows the walls to sag. To stop the walls from sagging you need to address the reason the floor edge failed.
