Thanks, this has been a question i've been thinking of for a long time. Gas welding is more portable, and more capabilities than carying around a mig setup on a rig, with the gas set-up being able to cut, bend, and weld, it just seems like the right choice for the on the trail fix for me anyway having more experience with gas, but the question of laws and transportation always comes up, especially in CA. I'm sure it wouldnt be too difficult to have a hard mount area on the rig to keep it safe, especially in a pickup, no worries of the leaks causing you to loose conciousness.
