2000 Excella 28' Interior Bedroom Measurements

[chicduckie]

I have been searching online for a while and have the owners and part manual.
We are about to hit the road this summer in our new AS and want to add temporary bunk beds to the twin bedroom. Is there a schematic of the AS interior with measurements anywhere online? Has anyone done this already and has their measurements the would be willing to share?

We are just trying to come up with design ideas based on the size of our kids and the measurements. We also are trying not to lose too much storage.

Thanks for your help.
