    In Ontario you get 42000lbs with a 72" spread. Its an old fashioned spread but in some applications it can work. Common on triaxle dump trucks.

    Day cabs for day work.

    We don’t run in the city so it doesn’t matter about easy driving.


    Less weight I would guess.

    I run MB, ON and MN with triple axle trailers, B trains and 4 and 5 axle straight trailers. The only place that big spread will increase your weight allowance is Ontario on a 4 axles or less trailer.

    It has heavy right in the title.

    usually heavy haul means overweight permits anyway.
    Some states you can buy an annual blanket permit that allows you to skip purchasing a trip permit for each trip. And with a blanket permit you’re responsible for your own route planning to not get on a road that’s too skinny or hit a low overpass .

    That only applies on the trailer. You have to have a spread of 6 feet or more to get the 40k rating. Definitely be easier to chain that truck though LOL.

    I could be wrong and I'm sure it varies by state but I believe you have to be 10ft 1 inch to get 40k. The weight goes down incremental to the distance in spread
