That's unnecessary. AMFU will work at 1%, so just reboot it if you somehow manage to completely destroy your AMFU. Bring enough mats to synth ammo.If you can afford it, fill all of your empty spaces with AFMUs when you go exploring.
And cargo racks are required if you want to bring repair limpets. You don't have to bring the limpets but you need 4T of space to synth them.
