I can definitely update when I wire it. I will just be using one continuous piece of Flexwatt. That just makes the heating more uniform. I use multiple strips on my current rack but one single piece of Flexwatt is much easier!
It is light enough that one person can move it with or without the tubs in it. I can weigh it on my scale later. I'm headed to dinner in a minute or two or I would go weigh it and update. Unless you're physically handicapped I would say you could move the rack by yourself without concern. I will update the weight with and without tubs later!
