The 321RES floorplan was added in 2011, but there are a few of members here with that model...
hopefully they'll see your post & respond.

In the meantime:
The online info doesn't mention 50 amp service, nor being pre-wired for AC in bedroom...
most likely neither are available.

"Pleated shades" are listed as part of the Camping In Style Package... I believe those would
be considered 'night shades' (only), not the day/night shades. Keystone's photos (& info)
show Roman shades in the bedroom, although that may have changed with the newly released models.

This 2012 ad shows the different curtains/shades in the bedroom.

A quick Google search found lots of photos for this model, plus a video.
I didn't find any info or photos to confirm the under-bed storage.
Hope this helps, and good luck with your decision.
