Forest River says: "When the weekend comes and you're ready for adventure, Rockwood rises to the challenge. Rockwood travel trailers and 5th wheels turn every outing into a party. These fun-inspired units are designed with family-friendly features that make your time together a celebration."

We show 2 pictures of the 2604 interior below.  The first shows the living area looking towards the bedroom. The large slide is shown on the left; this provides a lot of space and a real feeling of spaciousness.  You can see the layout on the floorplans lower down this page.

 
The second picture shows the arrangement looking in the other direction:  

 
Forest River have created a wide range of floorplans
for the Rockwood ultra lite travel trailer

The 2304S model (23'8"), one slide (all models have one slide) with a 60x74 flip queen bed. The 2501SS (27'1") has a queen bed and bunk beds. The 2601SS (29'3") has a long slide with a queen bed and a nice bunk arrangement. The 2603 (27'1"), the 2604 and the 2607 (both 29'3") both are without bunks but with a really spacious open arrangement. The 2701 is the longest model at 31'9" with queen bed and bunks and a lot of space taking advantage of the extra length.
