I know you already ordered the tote, but just to add another perspective... an often quoted minimum size for snake cages is that the length and width should be at least the length of the snake, and more for a more active species. For a snake over 5', this tote seems on the small side. Rough guess from forum posts is that the T8 is the most common PVC cage size for adult BP's, and it's 48 x 24". The tote is smaller than that, and the floor space is probably even smaller than the stated dimensions because often those are the outside measurements of the rim at the top - the sides taper, and there's a large rim to support the lid as well.

I know lots of people on the forum keep them in racks in much smaller tubs, and I do not mean to get into that discussion. But if you are not trying to care for large numbers of animals, why not give your snake as much space as you can reasonably provide? Yes, it's a little harder to heat, but it's not *that* hard. It's a little more expensive, but it doesn't have to be *that* expensive if you shop around carefully. A larger space also doesn't mean an empty expanse of floor. It has to have lots of clutter, hides, tubes, platforms, plants (real or fake), branches, etc. That sounds like a lot of work to clean, but it's really not. Thee snake doesn't poop more just because there's more stuff to poop on.

Your snake can still do fine in the tote you ordered, but it's just something to think about if you think about upggrading it in the future.
