I find it hard to believe an engineer/designer who puts a 3 inch hole in the sewer compartment and expect a 4 inch object to go thru it does not recognize a problem. I'm not an engineer, but it is fairly obvious to me that it won't work. If that engineer goes camping with his product, can he not see that and fix it? I guess the 'that's the way we've always done it' attitude is far too pervasive throughout the industry.

The manufacturers MUST encourage their people to fix the engineering and design problems that have frustrated so many of their customers. Right now, they have no competition to force them to change. But, the same thing the Japanese did to the US auto industry, by providing a quality product at reasonable cost, can happen to the RV industry.
Beaufort has it right. If the Japanese ever get into the RV manufacturing industry, the US manufacturers are in big trouble.
