I have a CT225, and what I did to make things easier was to back out the bolts that are supposed to keep the ROPS from vibrating until I could raise and lower it just by pulling the pins. I don't notice any additional vibration. Those bolts were so dang tight that you couldn't possibly turn them using the hand grips, and I was leaving my ROPS up or down when I really shouldn't because it was such a PITA. Now I can raise or lower the ROPS in just a few seconds.
As for driving into the shed, well, that's for you to figure out. It looks like you have relatively flat property, so there is probably minimal risk, but me, I feel naked without the ROPS most of the time.
