I expected to hear somewhere from 35-60k and up.
But I don't understand how that cost can be justified.
Why should a 8 foot sleeper cost as much or more than a new 35 foot fifth wheel RV?
Is there some type of special manufacturing process or DOT requirements to justify the cost?
We paid about $70,000 for our custom-built, 132" ARI sleeper in 2006 and I asked them the same question you are asking here. I pointed out that we are paying $70,000 for an 11 foot sleeper and 40 foot camping trailers can be purchased for half that price. What's the difference? I asked.
"Volume" was the one word answer. The sales rep went on to explain that trailer companies build them by the hundreds with standard floor plans and ARI builds them one at a time to customer specs.
I listened but was not totally convinced.
On the other hand, ARI builds a high quality product that can stand the rigors of the road. We have been our ARI sleeper for four years now and it has been the most trouble free part of the truck. It has been driven over 500,000 miles, including some of the roughest roads imaginable. Show me a $35,000 trailer that can hold up to that. Some of those trailers are really cheap and would not survive a drive in and out of New York City, let alone extended and repeated trips over washboard freeways, encounters with trees and even some off road travel.
Our ARI sleeper has kept us cool and refreshed in searing Mojave Desert heat and cozy warm in bitter, sub-zero winter cold. I would not trust a $35,000 trailer to do that.
Our sleeper seems to have more life in it than a $35,000 trailer would, or even a $70,000 trailer. If we replace our truck some day, maybe after it has ten years or more on it, it is a very real option that we would move our sleeper from the old truck to the new. In contrast, camping trailers seem to show their age quickly and with far less miles on them than our sleeper has.
Another consideration is the amount of use the sleeper gets compared to a camping trailer. We are using the sleeper almost every day of the year, all day and all night. Camping trailers used that much would not hold up as well as our sleeper has. They are built for occasional use, not the kind of use we make of our truck sleeper.
Regarding supply and demand pricing, there is more to it than that. The demand for custom-built sleepers has all but collapsed but the prices have not gone down. It costs a certain amount of money to build sleepers like this and regardless of how low the demand may be, there is a point below which the price cannot go if the manufacturer is to remain in business.
