Looking at a
25V online...wow! that looks familiar ! LOL
Although it has a dinette instead of the couch--didn't notice that at first.
From the image the rear storage looks to be of a similar size too.
In addition: they are both on the same chassis (E-350 if you get the 25V on a Ford chassis). LOL
I bet the 25V is a few inches wider..yeah 99" vs 94" hence the room for a dinette in the 25V vs the 24.1's couch (which also means there is a bit more room between the twin beds in the back as well).
Floorplans for comparison:
Four Winds 25V:
Axis/Vegas 24.1:
Note that I'm just pointing out another option. Pick whatever RV fits the most of your needs/wants. (We picked our RV because we liked the floorplan and that it had a lot of nice touches over our old 5th wheel--and it looked pretty unique to boot ! LOL.)
