I have the Sunseeker 24 ft. 2350 without slides and it works fine for 2 people and a 70# dog. My friend has the 2500 that he uses with 2 adults and 4 kids plus a dog and they manage to keep camping.
When using the dinette for longer term sitting like watching a movie on a rainy night, you need to support your feet.
I store two thin 1/4" 15x30 pieces of plywood under the dinette cushions to use as a leg support. I just pull them partially out and use them as extensions to support my legs/feet. Similar to the support of a recliner. I place a small throw pillow on it to act as a cushion.
The 1/4" ply has a little bit of flex to it which adds to the comfort. When you are done, just slide the support back under the dinette cushion and its out of sight till next time.
It really makes the dinette a lot more comfortable and I really do not miss the sofa since I added the 15x30 leg supports.
