I am going to join the chorus here and emphasize that a black tote isn't a good idea for either you or your snake. The opaque plastic totes like the one linked above are really the way to go. I use plastic totes for baby snakes and for some smaller juveniles while I wait for them to grow a bit and be transitioned into their adult PVC enclosures. Totes can be very nice for snakes, but they need to be properly set up.
Your dad may be concerned about fire danger when putting the heat mat under the tote, which is understandable. But a good heat mat that is regulated by a thermostat is safe, as you won't ever be setting the temperature over whatever is needed to create a warm spot of 90F in the enclosure...so your heat mat typically will never be set over 92-95 and that won't be an issue. It is a good idea to allow for a bit of air flow underneath, which you can set up by just putting the little sticky plastic or felt pads made to go under furniture legs on all four corners of the tote.
You CAN convert a tote to a front-opening enclosure with windows. A company called Specialty Enclosure Designs sells them, though others may as well. https://www.specialtyenclosuredesign...onversion+Kits. Photo below.
I have some concerns with what you are planning so far, and I don't mean at all to give you a hard time. I know you want the best for your snake, so I hope you will be patient with our suggestions and questions!
