I have to disconnect the tank and take it out of the plane. Then I toss a $20 at the line guy to have it serviced.

Though I'm still skeptical of the line dudes. I got screwed at ORF once. They dumped it but didn't re-fill it. I handed over the $20 and allowed the unit to be placed on the ground while I was tending to other duties. Only after line dude had walked away did I realize it wasn't fully "serviced".

Then I have to re-connect it.

So, I guess for me, it's a combination of "DIY" and "line dude".

There's no way I'd let someone outside of the organization disconnect or reconnect the tank in the back and drag the unit to the front of the plane. Too many opportunities to screw it up if you don't know what you're doing.
