U Ship is just another take on brokering transport
Although your individual experience may have been
favorable, the next guy will not get the same hauler
or shipping experience you did .....

Yeah, Jim, I hear you. I've dealt with enough trucking headaches in a previous career that I know both sides can be impossible sometimes. Mostly the side you're on.

You get somewhere to pick something up and it's nothing like the shipper said it was going to be.
If I was in the trucking business, this Uship thing would probably piss me off as I'm sure a lot of them are cutting corners everywhere they can and making it hard for legitimate truckers to make a buck.
I went through a lot of feedbacks before I committed. The guy I used "Mrroo", I talked directly to. Wasn't a lady at a desk getting bids accepted, then forwarding to a guy in the truck that has no idea what he's picking up. I just got a good "feeling" from him. Same as everything I've bought of eBay or Mud or the web.
You could "kind of" tell the ones that were out to burn you. Low bid, but then read the fine print of the bid details. "Must be on pallets", "will not do this", "this costs extra", blah, blah, blah..(Granted some of this is fine to make sure they cover their asses and don't get stuck being a packager as well as a shipper).
I was really kind of expecting something like "Mudship" before I started the process with them. Just a board for people to post what they need hauled, and a place for people going back and forth to pick up a few bucks dragging other peoples crap around.
At this point I would use them again, but probably just wait for this same guy to be making a run where I need. He's back and forth across the whole northern tundra quite regularly and he was so damn quick and willing to do what I needed, that I had to go that route this time. Got lucky, but maybe not next time with someone else.
The moral of the story: do your homework before you roll the dice.
edit: Just so everyone knows, Jim gave me a more than fair price awhile back to ship these exact same tires, but our timing just didn't work out. I got the same good vibes from him as well FWIW.
