We decided to go with a dual slide unit after renting a variety of lengths of class C rvs, slide and no slide, over a period of 10 years. This included Forest River, Coachmen, Tioga, and Safari brands in lengths from 24 to 32 feet.
During our rentals we found a 26 foot unit with a dinette slide to be the best compromise for us for length and maneuverability. These units also had corner queen beds. When we went to buy though, we found this 28 foot unit with dual slides and full basement.
Though it is heavier than a single slide unit it has the room to support long trips in comfort with adequate storage. It also has a full rear pass through compartment though only a couple of feet tall on the full pass through. The queen bed in the rear is walk-around with the rear slide out. The unit is also fully usable with slides in, only a couple of drawers are blocked by the rear queen bed slide.
