How RV manufacturers hide shortcuts from you


Look at the photo below. It’s the heater in a cheap RV. A couple posted this at RV Horror Stories. They were having trouble heating the front part of their RV. They checked around with a camera but couldn’t find anything wrong. So, “we removed the board under our bed which gave us access to the furnace.”

And this is what they found. To save labor, the RV manufacturer simply coiled up the heating ductwork to fit in the small compartment rather than shorten it to fit properly. The result is that the hot air had to travel much farther to reach the front of the RV, losing precious heat every extra foot of the way.

Of course it doesn’t help that the ducting is not even connected to the heater. It may have come from the factory that way or vibrated out.

But the obvious shortcut here is that rather than spend a little extra to shorten the ducting, the manufacturer saved on labor by coiling it up. And the buyers got suckered because they didn’t examine the “stick and tin” RV close enough before buying it.

In my 2018 Thor class C there is a gap about 1 inch wide you can see the road. Heater did not work, called an electrician none of the wires tucked up in the A/C area were connected. Very poor workmanship

My Thor class C has a gap at the passengers side about 1 inch wide you can see the street. None of the wires tucked in the A/C were connected. Very shoddy work on an expensive RV


This is exactly what I found on my Class-C. The heater hose was not hooked up to the heater and since there was not a hose clamp in the space or on the hose I can only deduce that it came from the factory unassembled. When you by a new or used rig, assume nothing and look very carefully under and behind everything.


I would think that this would be more in the area of either forgetfulness or laziness. If the mfg heater installer had shorten the duct, the remaining part could be used in another rv….thus a savings for the cost of ducting overall for the mfg. Also, pointing to the fact that the duct was not even attached to the heater, also makes me believe that this may be just another case of poor installation practice and maybe even isolated to this one rv.

A careless building detail for sure. What’s new?
Speaking of duct work, while nosing around in the guts of our motorhome when first purchased, I replaced all accessible flexible duct work with flexible INSULATED duct work. Made a big difference in the temperature of the heat delivered into the living space.

IMO When this kind of shoddy workmanship is discovered both the MGF and Dealer should be named. The dealer needs to know what they are selling. With enough bad posts, one would think the dealer would demand better quality. The MFG probably doesn’t care about an individual owner since MFG don’t seem interested in developing brand loyalty.
