    Talked to the engineers at Western Star. Their consensus for what I want to do is to go with the 10spd OD with 3.08 rears. They say I should be turning 1350 at 70mph. Will lose a little pulling power, but with the light loads it shouldnt be a problem.

    why on earth would you spec a truck with a 10 SPD? have you ever driven a 10 SPD?

    Cheap, durable and probably direct drive to pull those 3.08’s. It wouldn’t be my first choice

    I drove mostly 10 speeds for 35 years. I had a few trips in 13s, 5s, 7s, spent a year switching between 9s and 10s every night which gave me the tendency to go direct from 4th to 6th skipping 5th in a 10 but it worked for me for that year and I still do it. Super 10s, which frankly I just drove like a 5 speed. I took a KW with a 13 for a test drive the other day and frankly I wouldnt have one. so dont even go there. I used to ride with my dad back in the 60s - he had an 18 (or was it a 16? I was pretty little) speed 2 lever. Oh, and drove an automatic for a few weeks which frankly led me to quit being a company driver and go out and buy one. That was 2 years ago. Paid off the truck and got enough in the bank to spec out one purpose built for me, the way I drive, the loads I haul, the lanes I run, and write a check for it. I am almost 63, plan to retire in 4 years so this will be the last truck I drive (God willing).

    Edit:
    Just a sample of what I typically do:
    I load out of Minneapolis, on friday. Leave sunday night. Go to Ft Wayne, unload, go down to Indy and load, and Im home tuesday morning. I make $4000 (after fuel) for that 2 day run. And frankly, thats all I need. And sometimes I will find something short going to Chicago and back during the week for about $3k for this 2 day trip. But I usually just do the Ft Wayne - Indy - home turn. Ive been doing that for about 8 months now.

    3 weeks ago, I took a load out of Minneapolis (6000 lbs) to Marco Is, Fl (100 miles south of St Petersburg). Around 1600 miles. Parked the trailer at a tradeshow for a week so I spent a week bobtailing around Florida doing the tourist stuff. A week later, took my 6000 lb trailer 1600 miles back home. Made $12,000 for the run. (and Im going to be doing this one again in Feb, but to Orlando this time)

    I work smarter, not harder...

    That was much more information than needed, but alright. 10 speeds are hard on motors and forces them to work outside of their optimal rpm. either you rev it up to 1700 rpm every shift or you lug it accelerating from 1100-1200 rpm every shift. Either way it's not good and can be completely avoided by just ordering a 13 speed

    I don't know about hard on the motor, we have run 15 spd's for years with no motor problems, not my favorite tranny, but they work and are tough. I do not like a 9 or 10, but for light loads, just as good as any. Even if I knew for certain all I was ever going to pull was light loads, I would still go 13 or 18, just for the resale when I decided to get rid of the truck, retire or what ever. If for some reason that I hated a 13, I would go with the 9c, I hear about so that it can easily be changed to a 13 when I decided to get rid of it.

    Myself, I have always kept a truck forever, so wanted the most versatile and capable truck I could afford, tat way when freight changed, I had the bases covered without needing to change trucks.

    I bought a used Freightliner knowing I would only keep it a year or 2. I wanted to make sure it was what I wanted to do before I jumped in with both feet.

    I have only owned 5 cars in my life. The first was a beater in highschool (68 Cutlass S) that only lasted a couple of years, but I had a 75 Maverick for 11 years, 86 Thinderbird for 11 years, 97 Thunderbird for 17 years and now own a 14 Mustang. So yeah I keep them forever also. But this one I only plan to keep 4 years because thats all the longer I pan to work. If I work longer, then the truck will work longer too :)
