Sorry I did not post the age of my trailer. It is a 2004 Fleetwood Pioneer. We pulled in to my friends house the other night where we are staying for a few days. I opened both cylinder valves and tried to light the oven pilot and nothing. I pulled the cover off the cylinders in front and found a lever so I moved it to the down position and in the dark with a flash light the best I could see was MAYBE a green ring came up in the plastic housing and then I was able to light the pilot. I have not checked it since we got here but will be doing that today. We will be getting the cylinders filled today and changing over the tongue jack and a few other little things on the trailer before we move on to AZ.
