I think the model number is 1761. The camper box is about 9 feet and few inches long and about 6 feet 6 inches wide. I will get some pictures in the next week and post them here so you can see what I am working with.
Another thing is that the furnace as a 'click' that goes on when its running. I sounds like there is like a pebble in the fan or something and it's hard to sleep through. I dont really know much about doing stuff with the furnace, but if I can fix it myself I would rather do that with my dad's help. (He is a smart guy, just not sure on the procedure of this exact issue). I guess if I have to replace the furnace down the road I was thinking of one of those radiant catalytic style ones. I am just not sure how that all would be for use in a Pop Up where its all one area. I dont want to have the gas kill me or something.
Sorry I am so sketchy with this, I will get the info I can this week. And I really appreciate all your help!
