We have a '75
Trillium 1300 and we recently removed the
furnace. (We don't have much need for it in the south but we need the storage with the kiddos.) With the
furnace out, we can clearly see the
propane lines. From the hitch to the bumper, it appears the first goes to the
fridge, second to the burners on the stove, third to the
furnace (which we'll now cap off), and now we have a mystery third line which is much thinner and appears to travel up above the furnace hole between the
fiberglass backsplash and the
fiberglass shell. What does this go to and what is it's purpose?
