I have to admit the first thing I thought was 'Man that is so redneck' as well LOL.
If I may make a suggestion; no idea where you live, but that set up makes me cringe when I think of some of the storms I get here. I'd get some good Paracord and tent stakes, just to ram it into the ground, like one for each corner, and then two on the sides or some thing. Shouldn't cost much and might save you a few hundred dollars of pain if a storm whips through.
Like I legit saw a min fridge, inside a small shed -attached- to a house get thrown across a 20 foot yard before by a storm. I don't want to imagine what my MES could do if I put it up on a stand. <Do like your idea though...I want to raise mine up, but the stability is a concern to me!>
