A few tips needed on appliances in our new 1975 14ft scamper

I had a early 1970's era popup. The gas tube on the pilot light to the furnace was so small it would take centurys to bleed all the air out of the line to get the pilot to light. I hated trying to light that pilot light so much - it was inacessible, had to contort to get to it, and it would take forever plus a day to get it lit.
