2019 International lt midroof Good aplication for flatbed?

You probably will want to pull that roof fairing. And find out what the tare weight is. 53,200 is the combined axle rating, not how much it weighs.

 

Thos internationals are light. I ran one and with a 53ft combo step I was right at 30k.

Ive got a 450/1650 ISX right now with 3.55's and its low ok powerwise, it'll run as fast as you want on the flats but falls on its face on hills.

 

2.79 rear end on a 450 hp motor is for pulling a van down a flat interstate (i.e. Mega carrier linehaul).

Pulling a skateboard, you'll be running close to 80,000 lbs gross every day and will be slowed down significantly on any sort of hill (ruining whatever fuel economy you make up for on flat ground).

Also, the fairings are going to impact your ability to go off road on job sites and I'm guessing the rears probably lack full lockers.

A proper flat deck OTR truck is going to be a minimum of 500 hp, 3.55-3.90 rears (higher for larger gross weights), 6x4 drive, full lockers and at least a 13-speed. No plastic fairings, lots of frame space for front overhang and toolboxes, long sliding fifth wheel.

There is nothing wrong with pulling a deck with an aero cab, but at least find one that can do the job properly.

 

If the main concern of the gearing in the rear ends is the weight that the truck will be pulling, if limited to 80,000 pounds, then there is no issue with the 2.79. We have setups that are very similar to what is described that do just fine hauling 80k, hills or no hills. That engine will love 1100 rpm cruising speed at interstate speeds. That gearing and transmission will set it up to do just that.

 

I agree with the fairings and frame space but we get along with with just the power divider lock and 450hp. Only time I've gotten stuck I wouldn't be getting out with anything but a yank anyway. It'd be nice, but not required unless you're deep in the oilfield.

 

Depends on your company's yard, lol. I've had to lock the power divider and the rear diff lock numerous times in the past few years. Mostly ice and snow issues, but mud as well from time to time. Delivering grain bins to farms and picking up straw bales in the field they also come in very handy, especially when your truck is axle-deep in mud.

 

Full lockers won't help your truck swim.
