I chose the 16UL over the 18EC because the rear cargo area is completely open and almost 20 inches wider than the 18EC. Very similar to the smaller Weekend Warrior and Eclipse toy haulers. The 16UL has a front kitchen (right side) and front bath (left side), and a rear, loft electric bed. I'm convinced this has a positive effect on mileage. Has the front, aerodynamic 'dome' on the front instead of the usual flat face used on the standard Work & Plays.
Looking directly from the rear and the front it looks exactly like all the Ultra Work & Play toy haulers (18 to 30 ft), it's just shorter. A little heavier than other toy haulers with a similar cab size, but for good reason-stronger frame (more floor bracing), 5k 6-bolt axles (instead of 3.5k 5-bolt), fiberglass/plywood siding, etc.
