viperdave....you're supposed to be lurking and not creating more work for me
This is something I have been looking in to. I think it is actually a combination of things.
1. The dream dinette is designed for a certain geometry. From floor to table height. However if there is wiring that runs along the wall, (wire chase) the mechanism gets set 1.5-2"" higher. That in an of itself is not a huge deal.
2. The dinette is a "sprung" system from our supplier. I think it may sit "too soft" so your normal 18" seat height, becomes more like 16".
Add those two things together and you get a table that is 4" too tall.
Just as an FYI. 30" is standard table height. Standard seat height is 17"-19", we assume 18" is ideal.
I was around when the Dream dinette got designed. We had a similar issue where the table height due to wire chase was too high. they came out with a modified geometry that set the table 2" lower, for situations when it had to be set higher. While I recall this situation 8 years ago, the supplier has been less than helpful in responding to this issue.
