Before rigging up this RV furnace, I used to use two of those tank mounted heaters like these.

They worked ok, but even with the garage door opened a little to allow ventilation I would start feeling lightheaded after being out there for a few hours. The amount of moisture they put out caused a lot of my cast-iron machine tops to rust if I didn't wipe them down with WD-40 after running the heaters.

Like Ron Selzer mentioned

seeing that the RV furnace vents the exhaust outside there's no added moisture. The other thing that's nice with the RV furnace is that it uses outside air for combustion, so there's less of a concern with paint or stain fumes.
