small fifth wheel
I don't know anything about those brands, but I decided on a Terry Lite 25' - lots of room and the best floor plan within my weight limitations. It has a small manual slideout which makes a significant improvement to the usability without major increase in weight. About 5300 lbs dry weight, 7200 GVW (Maximum weight). Theoretically, this is at the upper end of the range for a 1/2 ton pickup, but I wouldn't advise it unless one has airbag spring enhancement, engine AND transmission coolers, and a good engine/gear combination.
Quality and reliability are of this unit is fine, within the obvious limiations likely to be found in any lightweight trailer. In order to make it lightweight, they take every opportunity to keep the weight down. Thin interior walls, flimsy and minimal cabinetry, and the use of plastic (for drawers, etc) are to be expected and are the cost of the lightness.
