I don't want to bash your set up, just want to show other options, Swag makes great products and I have a few of them myself. Personally for me I am to cheap to spend $125 on an exo cage for a plastic tub. I recently fund a similar size tub for the same price that is much sturdier then the action packer.
1 thing I always hated about the action packer is the wasted space along the bottom sides of the tub where the sides are nearly 2 inches narrower the the top. This tub has a deep locking lip of sorts which leads to a more weather proof seal. I got mine at Sportsmen's warehouse for (I believe) $18
