I have gotten a LOT of responses to my post last night about cup holders.
Unfortunately, I have had to turn more people away than are actually going
to receive them.  This tells me that there is a big demand for this sort of
thing....

well, if you don't mind spending a bit more, Steve Lashely at
www.eurocampers.com stocks a couple of different dash mounted cup holders.
One is $25 and the other is about $95, but has a fold-out table.  (someone
referred to one of these recently in a post).

I'm not sure about which years they will work for, though...

PS - I have no affiliation with www.eurocampers.com, other than being a
happy customer (bought my Paulchen from Steve last year) YMMMV.

Contact Steve for more information.
