If the toad has a receiver, then haul the smoker on the receiver hitch of the toad. If the toad doesn't have a receiver, then add one. Class III 2" Receivers with 500 pounds weight-carrying capacity are available for almost all toads. For example, if your toad is a 2010 Honda CR-V, here's a receiver with at least 500 pounds WC capacity that will bolt on:
Rigid Class III, 2 inch Receiver Hitch R3-0382
Another, if your toad is a new Ford Escape:
Draw-Tite Class III, 2 inch Receiver Round Tube Hitch 75758
