Need recommendations on keeping a GABF in sterilite containers

[Quijibo]

Morning FF community, been a while since if been on here. To give you a bit of background information I am a US Army Soldier. I travel a lot, pretty much jumping to a new state every 2-3 years. Because of my job situation I need to relocate here in a few months and I have moved my GABF into large sterilite containers so I can move a little easier. I do get the benefit of movers to come in and pack up everything I own but they are notorious for breaking glass enclosures/fish tanks so sterilite till i get to my new location and see whats broken. I did have my 3 GABF males in one 40g Breeder. Surprising they did very good, no fighting, they all seemed to have a territory staked out of where they ended up digging in the dirt(I do separate them to feed). Later on I will redo their large enclosure.

Questions is what do you think about this setup, and how I can improve it besides the size of the enclosure?

Enclosure size: 66Qt I think
Lighting: UVB in an old fish tank light fixture
Heat: Heat cable under the enclosure, 81 degrees + or - a degree in different spots. Water temp is around 76-78
Substrate: Cocofiber/fake plants
