Admittedly I have lived in the Denver area for 54 years, not Colorado Springs, but our weather varies very little from theirs. My house is at 5800 ft. and Colorado Springs is at 6000 ft., but we are both at the foot of the mountains on the plains, not IN the mountains.
Yesterday our humidity got to 70% during a thunderstorm that dumped 0.68" of rain in 3 hours (I have a met station in my backyard) and our high temperature before the storm was 85 degrees. A week ago, our high temp was 97 degrees and the humidity was 15%. Have you ever seen a humidity of 15% in Florida? June here is very little different than July--maybe a little cooler and a little more humid on average, but not much.
As far as wind, in summer it generally occurs in association with cool fronts and thunderstorms and gets to perhaps 40 mph. But we don't have 100 mph chinooks this time of year and we have very few tornadoes compared to all those states you will have to drive through to get here. Chinooks occur mainly in November and March and tornadoes in April-May. And, BTW, your RV will be in 65 mph winds all the way to Colorado if you are driving at 65 mph on the Interstate highway!
