The question was not about other types of tables, it was about the EZ-Reach table.
The dinette seat in our E23 appears to be constructed in a similar manner to our E19.
The manner of installation followed EZ-Reach instructions (provided above) and has resulted in a very secure installation.
This is my knowledge from our first-hand experience with the EZ-Reach table installation. If someone wants to tack on additional framework, nothing says you can't, but why make it more complex than necessary if following the EZ-Reach instructions provides a strong, secure installation? If there is concern, perhaps a quick call to EZ-Reach would help.
