So I'm working on getting the camper ready for summer and while troubleshooting an oven problem, I decide to remove the range and work off the bench. While looking for a possible vent obstruction, I notice this
Its the gas supply line for the water heater, poorly routed under the range then up the side before exiting to the WH regulator
All it took was a very light push to penetrate the left over wall with a scribe. Could have been real interesting.
