Routing your own furnace vents...
My trailer has in floor ducting. The most important of the three vents has never worked that well, and has gotten worse. Now the floor actually gets warm where the duct is likely leaking. I thought...

Hi, If you open up the inside and outside access to the furnace and look carefully you will see that more than likely your furnace has some round plates about 5 inches in Dia. on both sides and probably on the front (the side facing into the camper)These are for the round flexible ducting.
You could install these and make openings in strategically placed cabinets. However this means taking the furnace out which sounds daunting but is pretty simple actually.
I just removed my furnace, cleaned it and removed a mouse mansion in the main duct and rebuilt the furnace mounting (which was one of the few things on this trailer I have found done truly badly but could have been done by an RV dealer on repair rather than the factory)
I have floor ducts also and before I would do any of the above I would get a plumbers snake and attach a wet rag to the end and run it through the ducting. You may have a mouse who has constructed a mouse mansion in your ductwork.
As for shutting down certain ducts this is not a problem for the furnace unless you shut down more square inches in exhaust opening than there is at the furnace outlet. Part of the problem with so many ducts in a small area is that you are experiencing a "pressure drop" in the air flow resulting in less force coming out of the ducts.
I also agree that a camera look in the ducts might be a good idea to see if there are holes.
Now my water pipes all run inside the cabin except for a short run from the water inlet/water heater to the Kitchen Sink area. I added extra insulation for them myself where they can be reached. I can use water well below freezing as long as the hose doesn't freeze up.
Good Luck
