Sorry for strange combo of questions, but we need to replace our bottom of the range really rather useless coolbox with something that might, at a pinch, actually keep food cool. Don't want electric, looking for something around 30L. Any suggestions please? Anyone with experience of the 5day Coleman? Also we are looking for a lantern that we can hang up in the tent but that has the light on the underside (does that make sense?). I can only find the ones with the lamp bit on top, and when trying to read in bed the shadow of the casing falls on the floor. Does anyone make an upside down lantern we could hang up? Thanks in advance oh MN camping gurus....
