New furnace install

My Honeywell wifi's will go down to 40, they are easily adapted to use in a coach ( wifi in the coach is needed of course for their intended use but they can be operated manually) they work great

Instead of cutting another hole is there any way to use some sort of double wall pipe?  Heat going through the middle and return from living space going through the outer portion.  Seems the heated air would stay warmer and the return would be preheated.  Then insulate the outer pipe also.  Just an idea.

I forgot about the exhaust and the bouncing.  BB Transit FE is a front engine, short wheelbase (front axle behind the door) flat nosed schoolie with a long rear overhang, the back of that thing is going to ride as rough as an 8 year old kid would want.  It's going to be a problem, without a doubt, you could probably launch stuff off the back of that bus...  Exhaust would normally be right under this box, and the rear low pressure area will trap it there and try to push it inside the bus.

- I did do some tests on the bouncing - it has air suspension so it's not too bad - I added rather large, rugged braces on either side of the Reese hitch to support either side of the box mount base.

Also, I moved the exhaust to exit the driver side behind the rear wheels but back more. Mostly I will be running the heater when the engine is NOT running but I will be doing some stink-and dye testing to see if anything is creeping into the cabin through any means. In the end, I hope to have the furnace sealed mostly with only the hot air into the bus and the return air coming from the bus into the furnace "inlet" area.

As mentioned above - it seems to be working so far but I am curious to see if adding the "return" air duct will allow more heat into the bus (physics says "yes-duh") - But I just want to see if there is a noticeable difference.

Thanks to all who have posted and encouraged. If I haven't mentioned it before - this is as much a prototype test as anything to prove out some functionality ideas to make room for other ideas on the drawing board. I expect that I may move the furnace into an "underside tool box type" compartment (custom made) before next winter when I gat the bugs worked out of the other ideas in the works.

When I "finish" this project - I may be posting the build on the bus projects page for others amusement :-)
