If you get up at dawn every day, and are home to refresh with unfrozen water two or three more times each day, you don't need a water heater. Otherwise, plan on electricity and water heaters!!!
My chicken tractor is in use only for meat birds, in spring/ summer, very close to my house and fenced dog yard. It gets moved a bit every couple of days, and has worked for us. As a permanent coop, no way would it be safe from digging predators. They would have the time to scope it out and dig under.
A hardware cloth floor would add weight, and cause injuries to the bird's feet when you tried to move it.
There are good permanent hoop coop designs shown on the forum, so look them up.
A run made from cattle panels, attached to a safe coop, would work. Making it tall enough to comfortable work in could be tricky too.
