We just "signed on the dotted line" for a 2013 21FBS Caliber and traded in our hybrid.
Actually, I was surprised DW went for it w/o a couch, but she liked the storage, bath and kitchen layout.
And since we camp in State campgrounds that can be tight, I like the shorter length (26-1/2')
NB - Heartland recently started making this model with a deep slide and 3 steps, it seems so much roomier than the shallow slide unit we first looked at.
After 6 years in the hybrid we had a list of "must have," "nice to have," and "don't care" features. We looked at Jayco, Forest River, Coachmen, Dutchmen, Trail Runner, Evergreen, and a few more manufacturers but came back to the 21FBS.
You didn't say what you're towing with, but it's into the 1/2 ton pickup or Tahoe / Yukon / Durango SUV range. A TV with 5,000# tow capacity won't cut it.
