I am sitting in our 27-5L right now, watching tv while it rains. The rear pantry is the only thing blocked when the slide is in, the same as our 2000 27-5L which we had for over 8 years.
The tv angle is perfect in this 27-5L, but the tv is limited to 32".
I really like the MORryde pin box. I can't feel it move, but looking at the dust I can see that it does.
We have the older type stairs which work much better for us.
We were also considering the 28-5C, but the tank sizes were a no go for us. Because the slides cut down on space for tanks.
