Many of the 2015 models do have 2 or even 3 steps. I'm not sure how Keystone "got away with it" like they did, but RVIA doesn't say much about it, however the "national building code" has a 9" maximum rise for steps. Ours were upwards of 11".
I agree, it would be so much better, both in function and in looks to simply have moved the upper deck cutout forward 2 or 3 inches and installed 3 steps when building these things.
Both my DW and I really find it much easier to get up and down now. We both were having knee/hip problems in Galveston just from climbing those steps. I wouldn't think it made that much difference, but it does.
Ain't "getting old" a "pain" <sigh>
