    oh they do...but the pay wasn't like worth the time, and aggravation of searching for a dolly (that was road worthy), or searching for both trailers, then tearing them apart, docking them...

    too much BS.....for not much more money

    I have to admit, the hardest I ever remember laughing was listening to a guy talk about putting together triple pups and had no idea what he was doing!

    I only had to deal with one once. Terminal I was out of had training for long doubles guys at the pad at the Ohio turnpike 118 cash box. They all got up there for the so called training and realized they didn’t have a tandem dolly at the pad! I had just gotten done with my city run and they asked if I would mind running it up there. I was hourly, it was dark , seemed like easy money. I ended up spending 20 minutes finding a tractor that was plumbed to bobtail with just a dolly as R&L doesn’t do that and only long doubles tractors were plumbed the right way. As I said, it was dark and a ways up a two lane state route and I wasn’t comfortable going that far with no lights on the dolly. There weren’t many long doubles tractors and most of the Prima Donnas that drove them were SCM favorites and could lock there trucks when they went home , rest of us would’ve gotten written up. But any way, finally found the locked tractor, tracked down a hidden spare key for it , got hooked and ran it up to the pad where about 8 guys were standing around on the clock doing nothing but waiting for that stupid tandem dolly they all forgot about. Typical R&L “training”. Just getting that thing lined correctly to the tractor was a pain as back window was filthy and salt crusted. Couldn’t nudge it very well the way you could a single axle to get it to drop on the pintle. Didn’t even want to try stringing a set of long doubles. The guys that did it were pretty good. I’ll give them credit for that. Not trying to bust on the young lady in the video but just saw too much opportunity to get hurt. Like I said not her fault, but the company I assume she was hired by.

    We had a double tounged tandem axle dolly. It was a prototype deal. Now that was BS! It did pull like a B train(no wiggle) but not worth the hassle.

    I’d hate to see what they’d do trying to put a jiff lock dolly together with a single screw jiff tractor

    I saw a few things that I wouldn’t do.

    The tail trailer was too high. That allowed the dolly to get under it. I had one this morning try to run away, so I had to hurry up and lower the trailer to stop it real quick. It looks like when she originally spotted the dolly she didn’t allow herself enough room to work.

    First thing I connect is the chains. Next, air lines to the lead followed by air lines to the tail. That way I can open the valves and get the air system charging up sooner.

    I didn’t see them check the valves at the back for air all the way through. Granted, that’s a bit of a problem though on a 579. You need a way to send service air through the system and hold it, and 579 Petes just don’t have decent way to do that with their type of trolley valve. I jam a flat head screwdriver in mine to hold it down. I suspect these two characters haven’t figured that out.

    You can just hold that lever down for a few seconds and it will keep pressure on the brakes when you release it.

    I think I’ve seen those, I think Gordon Food Service tried them out for a bit. They’re a large restaurant supply and food provider up here in my neck of the woods. Seen a set up in Michigan dump trucks that had chains you could hook from dolly front frame corners (tandem dolly) to rear corners of lead bucket that supposedly kept the dolly from turning much so as to facilitate backing double buckets or a straight bucket pulling a full trailer at dump sites. I think that was an in house redneck engineering thing with a single company however
