What not to do when you "Stow" Your Caravan

So we learned the hard way why not to leave dried food in your caravan when you stow it away for 3 months! After three long months of our caravan under wraps for the summer here in the UAE, we have finally unwrapped her to get her ready for the new caravanning season here in the United Arab Emirates. A thorough clean inside and out to get her ready. But what did we do wrong? I guess being newbies at this you don't know everything about caravans but we will certainly not do this next summer ha ha! What things have you done wrong when stowing your caravan away, do let us know, we would love to hear from you.
