I think if you are going to mention ability to roll these things around when full it is important to mention the actual unit you have, the type of leg extensions if any, and the bracing shelf. I was thinking @Jag75 has a CF5 and @mongoose33 has a CF10.
Each size up has a correspondingly higher center of gravity. It would be interesting math problem to figure out how much higher but I guess an estimate is ok. My CF15 likely weighs about 60 pounds empty with all accessories mounted with center of gravity about 25" off the ground. With 18 gallons of wort added it's now 210 pounds and center of gravity maybe between 35 inches.
As I understand it, the increase in weight and height of center of gravity compound when considering the potential energy of the system. Using an online calculator I see my unit empty would have 125 foot pounds potential energy while full 612 foot pounds. I'm careful around this thing when it's full and happy to leave it stationary for sure.
