Is the Dinette size standard? Looking for Sightseer size

[ctcamper]

Forgot to measure the size of the dinette in the sightseer 31 the other day. My dinette is around 42 inches from wall to edge and 24 inches wide and I was wondering if that is a standard size?

That particular unit had the dream dinette and it looked shorter. There was no salesman around that had a measuring tape.
I'm trying to figure out if I can use my current drawers that I made which are 41 1/2 deep or if I have to make a new box for the drawer that is a little shorter.

Ok I checked with Service and it is fairly standard across the board for the larger rigs with the 42 inches, at least for Winnebago. I am good to go.
