My first guess is you will have to be a custom builder, marketing a unique product to a niche market.
The factories in Elkhart Indiana can produce 25 stick and tin units, 26 ft. long, with various floor plans, every day; day after day. They use the same component sources and have had years of corporate competition knowledge and in-breeding of personnel. Basically they know what will sell to the mass RV market.
A good example is the miss match of wood types, grains and shading one finds in the typical RV. Most of us would not buy a dinette set if the table and chair colors did not match. But it is not a factor in the RV trade.
Fortunately the sector of the market that really wants a cut above the norm is usually willing to pay for it. A classic example is Airstream, people will pay for a what they perceive as increased value.
If you are in the boat business, you know that to most people; a boat, is a boat, is a boat. But to some, certain features make a particular boat worth the extra cost. I my case it is Kevlar in a light weight canoe.
Good luck and I hope you find your niche. There is always room for a better mouse trap.
