Several model of Airstreams had just such a small kerbside table fitted as standard or as an option. If you go to www.airstream.com
and examine the floor plans, you will see some examples. You can buy them from Airstream, together with the narrow cupboard into which the folded table fits, which also has space for a couple of sun chairs for outside use. IIRC, the 25 foot classic has one. I see them occasionally at RV salvage yards, although often in poor condition. Search for "salvage" in the search facility at the top of the screen.
