With an RV of that age with such low miles it's not a bad idea when you get home to pull the valve covers and make sure all the cam follower rollers are free. That RV may have only had one oil change in it's life. Follow these forums long enough and you'll see the complaints about low mileage V10s blowing up. Without regular oil changes (with at least synthetic blend) those little rollers (which run steel on steel bearing surface) will develop burrs on their shafts. When that happens, the roller stops turning. The engine will still run until the roller and cam develop enough traction to "spit" the follower out of position, usually jamming a valve open, destroying the engine. Without this low mileage nightmare, V10s are +250K mile motors.
