I had a tank made from 3 doors from a bank (half inch tempered glass) and it weighed a heap. I moved it myself from in a fishhouse along a path and up a drive onto a trailer by myself, then unloaded it at the other end. The person I sold it to needed 6 large men to pick it up. It is not about strength it is about brainpower. I put down polystyrene and walked it on two corners, then moved the poly to the front again. Takes a few minutes but does save the back.
