Bought my first cooler

[Derek_OC]

Its called the Igloo Ice Cube. Just a big square cooler. Bought it for some box storage. Looks like it will hold about 5-6 boxes. Hopefully this is just temporary storage till i can save up for a cabinet. So i had a couple questions:

1) If i'm only going to use this a couple months should i really bother cedar lining the walls?

2) What RH should it stay at? (Lower or higher then my regular humidors)

3) Is there anything special i need to look out for?

I'm sure there is probably a link somewhere with all of these answers but i can't find it. Any help would be great.

Thanks,
Derek
