I think it would be really hard to get up onto the wing of a tricycle-gear RV without the step. The flaps would be at risk for damage, if not by a very tall pilot then certainly by an average or shorter passenger. I think the reason you aren't seeing any posts on experience with no-step on an "A" model is likely that it's very rarely done due to its impracticality for mounting and dismounting the airplane. I'm shorter than average and it wouldn't even be possible for me to get in my airplane without stepping on the flaps unless there was a step.
Suffice it to say…I have no interest in owning a tail-dragger, and even less interest in relying on one of those folding plastic stools. If I was out shopping RV’s again, the lack of a step on an “A” model, either side, would be a deal-breaker for me.
IMHO, YMMV, etc
