Hot Trailer!

Description

Question for those who may know... I have an enclosed cargo trailer. All my belongings are in there. Unfortunately, I can not get to trailer right now to pull items out. I have two 125 cu. ft. welding cylinders in there. One about 55% full with c02, other about 70% full with c02/argon mix. I also have ammunition for my firearms, c02 cartridges used to air up bicycle tires, and chemicals, i.e. wd-40, 2 cycle engine fuel, and some other chemicals. It is going to be 110 degrees these next few days. I am not sure how hot it will get inside that trailer. The walls are lined with 1 inch insulating foam, while the ceiling is just small gauge steel (20ga.?). I know the fuel is okay, as i read that the spontaneous combustion temperature is over 500 degrees, and I don't think it will get that hot in there, but I am unsure about the other stuff. Is this trailer going to catch fire with all my stuff in it? Thanks in advance.
