We have setup a good many fisherman with a point four diffuser system, Basics...O2 bottle (buy local welding shop), regulator, flow meter, hoses and microfine point four diffuser (pays for itself over time with less oxygen use). As far as safety I flipped a truck over and luckily I was not killed as all sidds and roof dented. The bottle was laying in the highway along with few thousand catfish. The valve was dented beyond repair but still intact. Lots less to worry abotu than an O2 bottle in your truck. Also not one time has anyone ever checked me or my fish after hauling fish for over 15 years.
