I appreciate that! :-)
Like you said, if you don't have the money, or work to support a second vehicle dedicated to welding, go with a trailer or tub rig using a skid. I guess it all depends on what you are doing & if you have the equipment to take a skid out of a truck. I didn't, so I went with a little trailer. It worked out good for me.
Heck, I fix & sell more welders than I weld with these days!! :-)
