Unless you’re pretty handy and have lots of energy or have lots of money, or have lots of family and friends you can get help from, I’d advise you to steer clear. if there was a leak and water damage was repaired, that’s not always enough. Mold and moisture is probably the number one thing that sends RVs to the scrap heap.
This one seems like the cabinets are the only thing that don’t need to be replaced, maybe the floor as well but since there was prior water damage, I’d want to check underneath that pretty vinyl and see what the subfloor looks like. Keep in mind moisture and mold is not just a structural issue, but a health issue as well.
at the very least, you should have it inspected by an RVIA certified inspector prior to making any decisions. They’ll be able to point out many of the issues you can’t see and will give you a full report, similar to a home inspection. That will give you more information about what to expect and help with negotiation if you decide to move forward with it.
