Jim, here is a picture of the table that came with our 2007 RT 210P, front and back.
I suspect your 2008 uses the same size table. The table is 24x33 and about 5/8 inch thick. It is made of some very heavy material of some sort and is white on the back and the same color as the kitchen counter top on the front. The finish is not but is similar to Formica.
The problem with the table for us is its weight. Nineteen pounds! It is very well made and serviceable but is heavy to store under our twin bed arrangement. I cut a table from 1/2 inch birch plywood that is 20x28 and that works much better for us being a bit smaller and it only weighs four pounds.
All you need is a 24 by 48 sheet of birch veneer plywood from Lowes or HD, a saw and some sandpaper. I rounded the corners and finished ours with a clear polyurethane and it matches the maple woodwork in our Roadtrek very closely.
