can't get furnace lit on vintage rv PLEASE help

I had one once that had a leak in the gas line to the pilot. After repeated times trying to get the pilot to light the gas has build up where the leak was and whoosh and boom... the whole area blew up.

You should have a fine gas line from where you push the button to the pilot light. Open that line and put a lighter there and press the pilot button. You should get a big flame. If not, your problem is before that, you have no gas.
