We have the Moryde steps that we purchased aftermarket. I love the fact that the RV does not rock when wife enters or exits. We have the handrail and like the security it affords with the stability of steps on the ground. As stated there are drawbacks to both types, but i'll clean the floor once in a while for safe sure footing going in and out.

We use it overtime we stay at Terry Bison Ranch in Cheyenne Wy. We used it in May this year there and they honored it. Have not had the opportunity to use others

Just reread your post and realized your timeframe was in March. I don't believe either of those are options due to the time of year, neither will be open yet. There are a few all year campgrounds on Hwy 24 on the west side of Colorado Springs but, I can't vouch for them. 

There is a Famcamp near The Air Force Academy. Another would be the Golden Eagle campground on the southwest side of Colorado Springs off of Hwy 115, other than that the campgrounds in the area are fairly expensive

I agree with Chiefneon, Buffalo Crossing is a great park with large sites and friendly staff. We stayed there 2 years ago and would be my first choice again.
