    So, I've my endorsement for a while, but never pulled doubles. I just got a dedicated account until Xmas pulling doubles. Most of it seems pretty strait forward, but im confused about weights.

    The lane is from carlisle pa to Syracuse Ny. So the only states will be NY and PA. The first trailer has one axle and then there is a single axle dolly and another single axle trailer. I assume 12 on steer, 34 on drives, but does the dolly and first trailer count as a tandem for 36 or as separates at 20 each? They are on separate equipment but less then 10 feet apart. I'm guessing 20 on the rear trailer axle? What about gross, am I still limited to 80K?

    Thanks,
    Cody

    80k gross,12,500 steer and 20k per axle ,on a single axle drive truck..which is what you should pull double with ..Sometimes the 2 axle drive trucks dont fit under the pups unless you have a sliding 5th wheel pulled all the way back and that can put you over too...I know it adds up to 92 k if you max out every axle so you cant do that...if the trailers are loaded correctly you can pull two with about 24k of freight

    Thanks for the clarification, so even though the dolly and first trailer axle are within 10 feet they each can hold 20? A single axle truck would be ideal, but im not buying a new truck for a 1 month dedicated account.

    Yes, first trailer axle and dolly take 20k each.
    Most of our stuff is single axle tractor - I see Fed Ex Ground runs tandem tractors.

    youll never get 34 on your drives w/that set up--pne thing to keep in mind w/a screw pullin a pup--is kingpindistance--you may find you have to slide your 5th wheel back as far as it will go--keep close watch on turning radius--both for back of cab to trl--and back of tractor to landin dollys
    and I really wouldnt worry bout weight--even when NY orr PA open their spots on 81--they rarely weigh--unless truck looks bad--ie bucket etc--or buldgin tires---
    Good Luck

    There are some roads in California that you can't pull doubles with a single axle tractor in the winter, US 395 between Carson City and Four Corners comes to mind, there are others.

    is there any bridge law that comes into play???? between his last axle on front trailer and first axle on rear trailer???

    we all know it's 20k per axle. but in order to haul 40k between those two axles. the spacing has to be 10 feet. if it were a flatbed.

    does that same scenario play out with doubles?

    Even pulling pups at 100% I got the bypass in FL. Never weighed a set when I did them last week as I am an outlaw. I did have to pull my light bar mudflaps off when the lead trailer wasn't a container chassis. Your fuel mileage will suck.

    Sounds like you will be doing a UPS or FEDEX thing for the xmas rush. You shouldn't have any reason to worry about weights if that's the case. Did the UPS thing one year and wasn't even close to gross at any time.

    Pulled doubles for two years back in late 90's.you will have no problem with axle weight,but you can get over gross. I was 36,700 with a empty set. Hooked to a set one night had 30k on the front 25k on back. Company paid all overweight tickets. Get to ga scales on 95 legal on all axle,but had to buy overweight permit. Dot not happy said if I had another 4k on would have to unload to 80k
