I doubt it, the flooring is installed before the interior.... AND the interior of two "identical" Airstreams might easily be off by a quarter of an inch. They're built by hand after all. If you do get one, test fit it first!!
Check with a flooring store, it has been several years, but it used to be you could get heavy duty grid paper designed for this chore... now? Someone probably has a laser that can shoot the layout and cut the tiles, boards, or vinyl sheet goods for you.

Today is a gift, that's why they call it the present.
