There are actually research studies that would tend to indicate that owning a 5th wheel is actually healthier than owning a Travel Trailers.
Seriousily!
The real difference in a Travel Trailer and a 5th wheel is that scientifically speaking, a 5th wheel RV owner will live longer than someone with a Travel Trailer. This is a quote directly from research from such prestigious Universitys as Harvard.
According to this report, your life span can increase at higher attitudes..such as a 5th wheels bedroom area which sits 6 or so feet above an average travel trailers bedroom.
I translated this from the article which was in Peruvian.
HERE!"5th wheel owners died from heart disease at less than half the rate of the lowlanders. Death rates were 61 percent lower for the men, 54 percent lower for the women."
At least thats the way I read it. But then I don't read, write or speak Peruvian.
This man, for example...is 105 years old!
