Have both styles - the traditional offset (Klose BackYard Chef) and a R/F smoker (Lang).
Each style has features that I rely on... but both are 1/4" steel.
Depending on your welding skills and the thickness of the existing steel on the smoker... might be a challenge.
However the WSM will be the starting smoker tonight for tomorrow's brisket on gameday.
