Side table & french cleat

I am looking at options for side tables. I like the idea of of french cleats but I also like the clever counter leaver approach used by Oregon Trail'r. I don't think it would work without the aluminum clip rail. I foresee a drink jug over balancing it and it coming off the cleat.
Can I do it with out adding a leg?
I may need a leg on the other side anyway as I will be putting the Webber Q on one coming straight off the side and the BBQ is pretty heavy.
