2011 KW T660 or 2011 Freightliner Cascadia for OTR?

DEF Trucks still have DPFs also.

 

Kenworth isn't what Kenworth used to be.

I've had KW and FTL, and the FTL seem to be better designed and built. I've had pieces of the interior come off the walls in the KW hitting potholes, and was run off the road in the Freightliner but everything held together.

Bottom line, drive them both, and buy the one that seems the best. Don't be surprised if it's the FTL.

 

The Kenworth T660 is the mainstay of our company's fleet. All in all, I'd rate them "fair"... however, I don't drive them... I turn wrenches on them. As far as DPF and DEF service, the components are pretty easy to get to on the T660 with the Cummins... cleaning a dosing injector is about a 15 minute process (whereas it's much more difficult with the PACCAR engine), DPF and DEF doser... not exactly a cakewalk, but fairly accessible.
Never worked on the Cascadia.
As stated above, the DEF trucks still have DPF and SCR. The exhaust goes through the DPF, through a crossover to the DEF dosing unit, then through the SCR, then out the end of the exhaust pipe.
DPF outlets are prone to cracking. I'd recommend you buy a couple DPF filters and a portable DPF cleaner (and an air compressor if you don't already have one). Other than that, the FL will have the better field of view... that's been my experience with FL trucks (I was, after all, a driver for over a decade before I started wrenching)... replacing windshields on the T660 with their split windshields is a very easy task... I'd imagine more the same with the FL.
That's about all I can really tell you.

 

Don't get t660. Very small on inside we run both and I'm in a t660, Cascadia has so much more room and I'm 6'4 240 and it is a pain to move around. Shifter so close to seat and so narrow up front always get foot stuck in between shifter and seat trying to get into seat.

 

I get around 6.7 mpg hauling average 44000 pounds cruising 64.6 which is all I can do lol

 

You're INSIDE the truck, the looks don't matter. Quiet is good. Room is good. Power is good. Chrome won't get you home!

A tractor is just a POWER TOOL. It has one purpose -- to help make you money. The only time you will see what the truck looks like is when you're not making money.

The one place to indulge yourself is selecting the seat you'll spend as much as 70 hours a week in. Comfort there is a top priority.

I've seen guys buy the fanciest POS (*cough*cough*Peterbilt*cough*) then drop another $50,000 on vanity junk, paint and chrome, then they wonder why they're not making any money with all the miles they drive. I bought an FLD 120 cheap, didn't put a penny into it other than maintenance, fuel, and an inverter to run my microwave and my rice cooker, and at the end of the first year I paid cash for a house.

 

I've never ran a def truck since they been implemented. DPF is all I've ever known since they were created.

Anyways DPF has done me well with the exception of a few times, wene I ran local. That being said, I couldnt get enough miliage to get the filter hot enough to clean it's self out.

You should be ok running OTR especially in the warmer climants down south. I only had to regen a a few times running in extremelly cold weather, or wene I idled the truck for a good amount of time.

Other than that. The DPF has done me good.

Ther is one thing, I had a some power generating problems with my Centry Class in extreme cold conditions . It kinda felt like injector trouble. But wene day light warmth kicked in, it returned to normal.I would assume the Cascadia would be the same.

I've ran two differant Pro Stars for the last 3 years, both have done me well. Both being DPF. Before that it always been Freight shakers. Two of them being DpF as well.
Sorry to get off topic.

Under normal operating within the last 4 years, I think I had to regen a few times running OTR. It'd be good not to idle the truck to much, as it causes build up in the filter.

I would say a 50-80 miles at high way speed would clean out. Youd just haft keep the idle down and outside of extremelly cold weather you probably be fine.
