    Hey Y’all,

    I’m looking for opinions on my current build spec. I do have the complete build sheet for those who are needing/wanting to take a gander but the important specs are below:

    Volvo VNL 740
    Motor: Volvo D13 500HP / 1,900lbs Torque

    Transmission: VOLVO 14 Speed / Ultra Low Crawler Forward and Reverse Gear / Overdrive

    244” Wheelbase (for Canada)
    3.21 Gearing

    14,600 lbs fronts
    Tires 295/75R22.5H MICHELIN X LINE ENERGY Z+ (14320 lbs capacity)

    46K rears @ 4.5’ spacing
    Tires: 11R22.5H MICHELIN XDN2 (24020 lbs capacity per axle)

    Main Driveline:

    Inter-axle driveline:

    Extra Info:
    11.81"X3.54"X.44" Straight Steel
    4’ 5th Wheel Slide - Rear Most Position is 48” behind front center axle

    275 Gal Fuel Tank
    18.5 Gal DEF tank
    Disc Brakes all around.

    5yr / 500k miles on Chassis/Wiring, Motor, Exhaust Aftertreatment, Emission components(350k), Transmission, and Clutch.


    Background Info:
    A friend of mine has similar truck except 13,200lbs front, 40K lbs rears, 13 speed transmission and 2.64 gears at 257” wheelbase.

    His empty weight for the same trailer is:
    12,960 on steers / 17,640 on drives, 16,160 on tandem(third axle up) / Grossing at 46,760lbs

    The trailer is an 3 axle extendable step deck, 43’ to 67’ plus 5’ “weight bearing” bumper. Upper deck is 10’.

    The loads are generators and other box shaped freight, weighing anywhere between 25K lbs (usually short) or 70K lbs (usually long). Rarely will pick up ann outhouse that is short <40’ but heavy 65-75K lbs. I would say average weights would be 46K.

    98% of the time, we drive loaded for 650+ miles then drive back empty. 2% of the time we will find whatever non-divisible overweight load we can or a 34K divisible load back home.

    Did I screw up and went too much? What’s your opinion?

    My friend has thinner rails, and less securement than I will. Which will add roughly 1K lbs extra on top of my configuration.

    I do plan on purchasing an extendable RGN with flips and a 2 axle jo-dog to pull heavier equipment in the future. That’s ~3 years from now.

    In my opinion you have speced a very good truck for the job you are looking to go with in the future. you may find it a bit heavy for what you are doing now, compared to you buddy but by running a bit light on fuel and working with you buddy to use the lighter trailer (if that is possible or practical) you should be competitive.
    TX2Day and gt4jk Thank this.
