My new MX and TEC140 needed shelter and this is what I came up with. It's about 4' long, 2' wide, and taller than needed, but should manage a larger scope sometime in the future. It rolls surprisingly well on the deck. My main concern is vertical stability which I hope will be ok. I have tried to brace the shed against the pier by using two u shaped pieces of wood...one at floor level and the other just below the top. The round white thingy shown in one photo is an all-in-one solar fan from Jaycar. More photos here:
