As far as what to carry for backup.....I've purchased this for 12v., which goes up to 40amp.

What would be needed for glass or other inline fuses? I realize every trailer will be different. These things are cheap, so what would be a good mix to ensure you have all the bases covered?
I do not want to be messing around on a Thursday morning and running to Walmart or Auto Zone. What is the best guess to have everything needed 'in stock', regardless of trailer?
