    If you proceed with your plan, could you document it? I personally don't have any plans on running to save MPG, but I do like looking at numbers. Hell, you might change my mind even.

    See that makes sense. I appreciate the information. It's quite different for long-haul cross country dry van - there are usually appointments, and the weekends usually turn most runs into lazy runs anyways.

    Like - if you pick up in Ohio on Wednesday, you sure aren't making it to Cali by Friday. And Monday delivery = lazy run.

    That is 99% of the time in flatbed, under those circumstances. I can count on one hand how many shippers and receivers work weekends, but I don't usually pick or deliver at big places. (think Nucor) So something like that changes things greatly. Also changes the rate. If the time pushes me below $1,500 per day, then I ask for more money. If I can't get it, I have a decision to make - do I want to haul it to get where I'm ultimately trying to go? Or do I let them keep it? And is it something interesting? (you'd be surprised how much that will affect my decision)

    That's the one cool thing about flatbed – interesting Freight. You guys get to play with weird big machines n jet engines n stuff.

    Conclusions so far: (68mph baseline)

    65mph - meh. Fuel savings statistically insignificant, and you get stuck among company trucks trying to pass you at +0.25mph

    62mph - nice. Confirmed 1.5 - 2mpg savings, and the Swift drivers get a confidence boost getting to actually pass somebody

    60mph - whoa. I'm getting over 10mpg with lightish loads. Just did North Platte Nebraska to Denver, uphill, no wind, 15000lbs - 10.6mpg! I get worse mileage than that in my 2002 Silverado with the horse trailer.

    But - it's starting to feel weird, everybody is flying by me, even the Swift drivers. I'm not going any lower than this.

    My first CA delivery. Arrived on Friday in Ontario CA.
    My first attempt to communicate with the receiver failed.
    I was not born in their Galaxy. After mucho per favor and muchas gracias Senor,
    a Monday morning delivery was scheduled. Loaded equipment lft in their care with the bills signed.
    A $5 taxi got me to the Ontario airport and I rented a brand new Ford Crown Vic for the week-end.
    In July 2001. I drove that car everywhere on the coast until Monday 8 AM.
    Down to San Diego and Up to SF.
    Best experience ever. Best Mexi food for $5 ever. Great memories to share with friends.

    Awesome! Way to make the most of it. ( except for the Crown Vic, I'm sorry they didn't have any good cars)

    My latest touristy experience was actually in your neck of the woods last month. Got to Toronto a day early, it was Sunday. Customer is near the Pearson Airport, so I walked over and took Pearson Express train downtown. Walked around a bunch, ate beavertails (dangerous), took the ferry boat to the weird island where all the hippies live. Good times. Didn't get to go up the CN tower though they wouldn't let my dog in.

    Crown Vic's routinely go 300,000 - 400,000 miles. They've got a pretty legendary engine/transmission combo.

    That is literally the only good thing about them, and the one thing you don't have to worry about with the rental car. Otherwise, they've got all the handling and driving dynamics of a 70s pimpmobile land yacht with none of the style.

    Maybe I'm just biased because I had to drive those #### things as a cab driver back in the early 2000s and they were terrible. Steering so loose and vague, trying to keep it straight on the highway was like herding a cat with a stick. I was so happy when they got us Camrys instead.
