For "small" I've always thought in terms of 8-foot or 10-foot box, and even alone I find the 8-footer kind of small.
I think we might be down to two manufacturers.
Thor's Jayco, for 2017 offering the Jaysport (essentially the same as base level JaySeries Sport of previous years). There used to be equivalent models from Jayco-owned Starcraft brand, but not this year.
Forest River's twinned Rockwood/Flagstaff lines, and the Clipper/Viking twins from Forest River's Coachmen brand, which now look a lot like the Rockwood/Flagstaff lineup.
Every time I've shopped I've been partial to the JaySeries Sport because the dealer selling them was one of the best in the area. I liked the 10SD in the JaySeries Sport, looks like the same model number in the JaySport is an upgrade in standard and optional features at about 1/3 higher price.
Equivalent floorplan at F-R is Rockwood Freedom 1940LTD or Flagstaff MAC 206LTD. Last time I was comparing them (2013) the Flagstaff/Rockwood appeared to be built on a much lighter frame than the JaySeries Sport.
Forest River currently has the largest selection, you need to figure out what layout meets your needs, may not be the same as those of an old guy alone.
