Ovens in RV's have a strange pilot sequence. There is a small pilot flame which lights whenever the knob is in the "off" position (not the pilot off, which turns the small pilot flame off totally). Then, when you turn the oven temp control up, there is a larger pilot flame which comes on and heats a thermocouple. When that thermocouple is heated, then, and only then, will the gas be sent to the main burner, and it is controlled by the thermostat. That larger pilot flame will be on as long as the thermostat is in any position other than off.
So, with the small pilot light operating, open the oven door and turn up the thermostat from the off position. You should see a larger pilot flame come on. If it does not, there is some issue with the thermostat. If it does get to make a larger pilot flame and still there is no main burner ignition after a few minutes, wait a longer time. I have a Magic Chef in a 40 year old Airstream which sometimes takes 20 minutes to start the main burner. Once it goes, it is fine, but having sat for so many years it is very cranky. I suspect a poor thermocouple, but have not replaced it. If I use that particular oven often, it does not take long to ignite, but the problem comes up when it sits for a year or so.
Thats the sequence you should see. If it does not happen, there is some issue in the thermostat control system, either a plugged large pilot circuit, or a bad thermocouple or bad thermostat itself.

If I remember correctly the oven has a thermocouple sticking out in the pilot flame. If the thermostat / thermocouple does not sense the pilot making heat, then the oven valve will not turn on the gas to the main burner.
That thermocouple might be the same one that you find on a gas hot water heater. If it is, remove it, and take it to Home Depot or similar store to find a replacement. I'd just replace it. They are cheap.
