To me, the seller clearly representing no rust on an RV that has obvious rust is a huge red flag.
If there is observable rust, no telling what there is going on that you can’t see.
The dealer may think they have an advantage, you having made a non refundable deposit and traveled all that way, but don’t let yourself be desperate.
You’re not desperate, and don’t take something you’re going to have to put a lot of money into.
Your decision, but this may be a learning experience rather than your dream vehicle.
