Ok, in answer to the most popular Q, and sad to report, the coach is not brand new. 2009 Heartland Bighorn 3580RL (thought I entered my "rig" info to appear as my Signature so the readers know my equipment but guess not, gotta redo) that I bought this summer. So this theory is ruled out, it is not "new furnace" smell.
Not stinky bugs as I well know that smell. Subcamper I really like your line of thinking. Tell me more! Like exactly how did you blow out the lines? I will follow your instructions. Assuming all know where the furnace is located and the 5th wheel RL (rear living) layout, the smell is predominantly (if maybe even only) coming from the shower/sink area floor vent. And funny enough, would be located directly above the furnace. And that vent, is the strongest odor. The bdrm vent is a very weak odor. Then, as you go down the steps to the Kitchen the 1st kitchen vent has no odor, but appears to not even blowing out heat. Going to test this further. Finally, the 2nd kitchen and final vent in the lounge both blow normal and no odor. So again, odor really just coming from the vent above the furnace outside the toilet door. And I do have an Underbelly as well, just not physically able to crawl underneath to examine. Which is another issue and the problem in the 1st place, how and where are the mice getting in? I have found clear evidence inside the coach and the damage they have done, but that is another forum topic.
Also, in another forum I read where a guy used his leaf blower and a "bunch of stuff came out". Now, would I remove the floor vents and stick the 2' nozzle down as far as I could and blast away? To exit? Outside the coach I have removed the Suburban grate and find 2 nozzles that fit into each other. So will "the stuff in the duct lines if any" easily exit via one of those openings? I'm just assuming one is exhaust and one is air intake, but I'm certainly no furnace mechanic. And these nozzles are only what, some 2" opening, so might even do more damage getting who knows what now CLOGGED in that nozzle coming from the much wider ducts?
Or........would I do the opposite, and use the leaf blower outside the coach from one of those nozzles? And inside, somehow try to figure out how to avoid any **** coming out to fly all over the place inside the coach!!! I have a total of 5 floor vents! That's me outside and 5 people inside sitting above the vent with a Hefty bag....LOL!!! Ridiculous.
I hope I addressed everyone's Q and advice and thanks again!
