How do I spec this truck for success

I would like to order a new 780 Volvo but would consider other options upon your advice. I want auto trans. and. super singles, the rest I need help setting up.

Drive all 48 states. Would like my best fuel economy speed at 65mph. I don't want to creep up hills going 30mph.Haul mostly 70,000 to 80,000 gross wt.

I am female and know very little about mechanics but willing to learn. Where do I start? Engine size? Rear ends? etc Please help me do it right

Talk to Fitzgerald trucks about a glider kit, unless you are planning to run California. I would seriously advise you to consider leasing a used truck for a year to get the hang of the business of trucking before spending $150,000.00 on a new one. Get some experience first.

Loose the mindset that you "don't want to creep up hills going 30mph." Going uphill fast is the biggest loss of fuel economy you will encounter on the road.

To answer the question: You will need to do as much research on all of your available options. However, I think the volvo I-shift can be in a direct drive configuration. The Volvo engines aren't great but still much better than the cummins. Here's how I would probably spec one.

Volvo D13 engine

Direct Drive I-shift

2.64 Rear end ratio (with direct drive trans only or 3.55 with OD trans., optimal around 62mph but not terrible at 65)

Single drive axle with tag axle if available.

Have a 2013 Volvo 780 with an I shift 264 gears 465 hp motor 6 by 2 axles wide single drive getting 7.7 mpg pulling refer coast to coast. What I would change...DON'T get single drive with tag tire wear and poor ride eat up what little u save in fuel. I don't know what the engineers at Volvo did but they screwed the pooch with their 6 by 2 configuration. I have driven deuce and ahalfs that rode better than this pile. Just drove 2000 mile with their system broken and truck rode good they "fixed" it and its back to riding like crap.

If your up to gross weight most of time and run much in the mountains I would stay away from that 6X2 configuration I had this configuration in my truck for 2 years and the only one that made money was the tire shop. I was running super singles and most miles I got out of set was 48,000 miles. It was costing me 6600 hundred dollars a year in drive tires on the drive axle the tires on the tag axle at the end of the year looked new yet.

don't buy a volvo if you want to climb hills.fitzgerald glider,with pittsburg power programming.we built our glider with a 3406E with pittsburg power.the series 60 is probably the best for fuel mileage and you'll get great pulling with pp program

All of you have given me a lot to look into and think about. I own a Volvo 2007 780 now but it is costing me $$$ to keep it going...it's tired and I'm tired of pouring money into it. Which I might add, amounts to a new truck payment and more sometimes. Even with all of Kevin's driving advice and tips, I still can't get over 6 miles a gallon.

I've been driving since 2000 and have experience, however I'm still limited and learning in the mechanical aspect of all this.....but God is not through with me yet! Calling Pittsburg Power is a GREAT idea. I'm doing my homework before ordering and will be checking back for more of your great ideas. Thanks everyone and "Master The Journey" as Kevin would say. Be safe out there.

Warmest Regards, Saundra (Dewdrop)

You have plenty of options:

1. The Volvo 780 (2.64 rear end, direct drive i-Shift transmission, D13 engine) would be ideal since you are planning to run California along with the other 47 states. You will need it to be a 6x4 since you do run mountains and occasionally may need a diff lock.

2. As others have suggested, check out Fitzgerald's glider kits. They work great if you plan on running everywhere EXCEPT California.

3. If you decide on the Volvo, You may also want to consider the XE13 Fuel Efficiency Package, which replaces the direct drive tranny with an Overdrive transmission that allows the engine RPM to drop to 1100 at 65 MPH. The XE13 is ideally suited for an over-the-road driver who needs better fuel efficiency and an automatic transmission. 2.64 rear ends are spec'd automatically with the XE13.

4. Look at alternatives like Freightliner's Cascadia Evolution, which can easily get 10 MPG when hauling 80,000 pounds, while having similar features to the Volvo 780.

There are plenty of great options. You will have to research them and determine what's best for YOUR operation.

Me and a friend of mine just ordered our 780's.

I'm going with ISX15,450hp,13speed manual,2.69 rears

6x2 with wide singles.

He,just like you,wants automated transmission.

His will be XE13 (D13,455hp,2.64 rears,6x4)and dual tires.

In this process I learned that auto transmissions are verry

restrictive when specing a truck.You can't pick and choose

rear ends,you can't pick and choose engine hp and torque

rating.Everything that involves i-shift is spec'd to run fast with

low rpm's(except xe13,only other rear ends are 3.08and3.26).

Same applies to Freightliner with DD13/D12 combination.

I added disc brakes and bose ride system to my truck and upgradded

all accesorie drives from standard(fan clutch,agm batteries,starter,

alternator,etc...).Price for my truck is$141k$,His is$135k$.

I did explore Cascadia before deciding,truck spec'd equaly to

mine was priced at$154k$(that's without bose ride system),

In 780 you get so much more bang for your buck that it was a

easy decision for me.

If you decide to go with Volvo and i-shift,you will find that xe13

is your best option,good luck.

If you would consider a different make of truck I recommend a Freightliner Cascadia with a DD 15 engine.

I run a volvo(2011 660 or 680 what ever it is)and i have the d13 with i shift with 264 rears and duel live axles..I have 24.5 low pros and have a hard time gettin over 6.5-6.8,the dd16 volvo had a bad rep but got a 1.5 mpg average better with a 13 355 set up...

Im not sure but i was told that the ecu for the tranny has learning capability but i havent seen it in my and the i shift is slow and sometime doesnt wanna shift till over 1700 with 10g in the box on the flats...Personally i dont like the i shift cause its a lil fussy and slow shifting,at times you evwn have to go manual and out smart the tranny ecu to stop early or late shifting..

For me i would a truck of choice glider with a pittsburge tweeked 14l detroit with all the power/economy toys kevin and his associates offer..

My brand new 2015 Cascadia Evo with DT12 is in the shop with failed Transmission. It's only done 9000km. So my confidence is a little shaken when it comes to the DT12 transmission!
