In a prior discussion someone pointed me to a great cover for the MES-30. http://www.amazon.com/dp/B004UQQP4K/ref=pe_385040_121528360_TE_dp_2
The original cover that came with MES was less than helpful at keeping rain, etc. off the smoker. This one works very well. I'm in Colorado and it seemed to do the trick for me. I don't know if it helps - but I also cover the connector on the smoker for the analog plug with a latex glove. Maybe it'll keep any moisture that gets past the cover off the electronics. Like yourself, I don't have a lot of places to keep the smoker. It's either on the deck or in the basement. Humping it up and down the stairs would most likely reduce its usage.
The cover is made of pretty heavy material and seems well built. I need to order one like it for my Weber gas grill since the cover on that is about shot after 3 years.
Edit: After being reminded of it. I finally got around to ordering one cover for my newer Weber (Genesis) and the old one. Thanks for the push. Everything will match now
