We purchased a 2012 Bullet 284RLS this spring (used). Only had it out once. The features we like are the layout, the big windows, 1/2 ton tow-able, laundry and garbage chutes are a nice touch, looks, big bathroom, a big improvement over the previous R-Vision Trail Lite unit we had.
Downsides; no black water tank flush (not a big deal but would be nice if there was one). The 'Polar Package' is not what we were hoping for, no extra insulation and no electric tank heaters. The package consists of a larger BTU furnace, enclosed underbelly, and heated tanks using the furnace. Haven't had it long enough for a serious evaluation but like it so far.
What model are you considering?
