Granted it might look unfinished and maybe it was tucked up further into the hole. The way the inside vents are arranged, it looks like that piping, ductwork whatever at least goes past those tanks. It does put out some good heat I might add. I think I'll let it alone as is. Second thing, I'm in FL and my camping in cold weather stops somewhere around 60 degree days. If we get a night that's lower than 50, it's really a cold night and I have little intention of going somewhere that's colder than that. I left that and want for it to stay gone.
Thanks for all the input from your folks.
