I want to thank all of you for your suggestions. Since the other gas appliances were all working, you were right that it had to be some problem with the gas feed for the stove alone. Since both burners were not working, the main supply to the stove must have had an air blockage for some reason. No, I would not stick anything into the brass orifices that could damage them. I was about to take the top of the stove off by removing the two screws that hold it in, but I had a brainstorm.
That was, why not try my portable car vac (armorall)? I plugged it into the ceiling circular orifice that is similar to the old cigarette lighters cars used to have back in the "good old days". Flipped over the builtin crevice tool on the vac, and vacuumed around each burner, figuring I might either dislodge something, or even create suction on the jets.
Voila! Both burners light...without disassembling the stove top!
Once again, this camper is happy, and can now eat inside our land yacht!
Again...A big thankyou goes out to all of you.
