Thsts easy peasy.. Looks a lot easier than hauling and delivering Acetylene like I used to. Very simple process especially the weigh in while onloading. I wonder if he got a scale ticket to add to his paperwork?
That really depends on the tank temp if it’s a hot or cold tank can affect how fast you can fill you have to be careful to and fill slower on hot trailers so it could be 30-60-90 mins
