If it sets up off the ground any, get you a sheet of styrafoam insulation and put it under the bottom drawer. Then cut another piece and put it on the back side as well. I got mine at my local hardware store and it was a 4'x8' sheet but it was only $7. You may get lucky and get a piece thats broken for a discount, my store didn't have any broken pieces. I did this last night after getting my first rack and noticing that it was cooler than the rest.
