don't listen to him. wood panel walls are sexy as hell. this is one of the most fuckable homes on earth.
now, no attic+attic vents (designed to trap and release rooftop heat and keep the house cooler) in at least a third of the house? less sexy. let's talk about the average and baffling housing decisions that this manufactured home has made!
So near the left side of the image, you can see a divide in the roofing styles present in this house. On the far left you can see a flat ceiling (known as a conventional ceiling), and on the right it transitions into an inverted V shaped ceiling, known as a cathedral ceiling.
Conventional ceilings have a pretty big gap in space between the actual roof and the ceiling in the home. This creates a big pocket of air, which can easily trap heat being beamed onto the roof by the summer sun and isolate from your home, which will thus remain cooler. In the summer, it can trap the rising hot air and ensure your house stays generally a bit warmer for a bit longer (though it's much more useful for cooling than heating).
Meanwhile, cathedral roofs essentially lack that attic space, meaning that there is no pocket for hot air to be trapped in, essentially allowing the heat from the roof to be immediately beamed into your home, without any meaningful barrier or insulation to keep it out. Just look at home much less attic space there is, and how much more difficult it is to even create that attic space!
Now, cathedral roofs do have strengths. Aside from the aesthetic value, they are very valuable for colder regions that benefit more heavily from absorbing sunlight during shorter winter days. But the mixed use between the two is just odd, and will create a notable temperature gradient between the opposite ends of the home.
This cathedral roof also looks terrible because, frankly, there's still a big support beat in the middle of the roof to help keep this double wide trailer together! See, manufactured homes come in primarily two sizes: single and double wide (rarely you'll see triple wide, and I would be concerned if someone made a quadruple wide). A double wide is literally two single wide spaces built out so that they can be transported via a hitched trailer, one half at a time.
The primary strength of manufactured homes is that they're cheap to build and produce, since they can be constructed primarily offsite, and can be easily transported by just sticking them on a big trailer and attaching them to a big truck and driving it to wherever it should be. Theoretically these homes can also be picked up and moved again, but usually after sitting still for about a decade you risk doing far more harm to the trailer by moving it than not.
Double wide trailers need special attaching architecture to keep the two halves of the home together, and to support the fact that, for the first several weeks of the home's existence, the peak of the house needs extra support beams, since it's been split in half. Notice how this triangular shaped shed roof requires support beams to keep that slanted shape. Double wide trailers are basically built using two shed roofs put together to make a steeple roof.
The other thing that cathedral roof messes up? The beautiful curved wall piece separating the kitchen from the rest of the home! Genuinely that curve is such a nice touch to the space, and it looks awkward as hell because the ceiling above it needs to be flat for ease of building that curved wall. Imagine trying to build a curved wall that is also a triangular at the top. Nightmare!
Thing is, they also cannot afford to remove that wall! Quite simply, it's an integral support beam in the center of the home that helps ensure the ceiling doesn't sag inward or risk collapse (especially integral in an open floor plan that has to be transported across a highway).
Look on the bright side, though. At least the steeple ceiling probably keeps that chandelier closer to 6 feet at its lowest point instead of 5.
