The legs that came with my smoker are designed to be mounted inside the unit and have a "notch" for the body to rest on. If I try to mount them on the outside, the unit cannot rest on the notch. Will the legs support the unit if the unit is not resting on the notches? I'm thinking maybe some heavier duty bolts than the ones the unit came with should do the trick. If not, are there any alternatives to the legs my unit came with that I can pick up at the hardware store? Thanks.
