I did a couple searches but couldnt find an answer. I am going through the design phase currently of my own build and wondering if it just easier to use a 20# tank that can be exchanged almost anywhere or go with the smaller 11# ? I dont know anything about getting those little tanks filled. do you have to go to like a welding supply or where do they fill them? so if you are in a strange city or out in the country at least with a 20# you could find a walmart to exchange it.
thanks in advance.
