Just out of curiosity how old...

Unique truck I noticed you don't have an ultra cab... With stand up sleeper looks real good .. Did it came from factory Iike that.espically a newer truck like that seems unique.

 

Ordered custom in 2005. Unibilt 63" COE.

 

The 63" walk in was available with the "flattop" main cab till 2006.
If you wanted a 70", you had to get "ultra".
There are 2 carriers around here that ordered trucks like "stacks", till they couldn't.

 

Nice truck .any chance you would have a full size pic that you could post of it?

 

Could you educate me on the difference between a Ultra and a Flattop dirthauler?

 

The ultra main cab is taller so you don't have to duck your head so low when entering main cab from sleeper.
Next time you see a flattop, notice the distance between the gutter above the door glass and the top of the roof. Also if the ultra has cab mounted horns, they sit way higher.
All factory flattops and daycabs (until 2012) had a lower roof on the main cab.
IIRC, the ultra came out in 96 or 98 available with a 48", 63" or 70" walk in sleeper. The non ultra was available, not popular for some reason, with a 48" or 63" walk in.
The 36",48" and 63" flattop all had the same main cab as "stacks"(unibilt).
I always hated the looks of an ultra (currently own one). Always told myself, if I ever have the opportunity to order a new one, I'd order it like "stacks" ,but in 2013 when I ordered mine, I couldn't.
Flattops are the best looking but I'm getting to old to deal with one LOL.

 

I had a 2003 with a 63" stand up ultracab. I wanted to convert to a daycab. The ultras that are converted to daycabs are hideous looking to me. So when I got the sleeper off, I took the (fiberglass) ultra roof off the cab and put an (aluminum) flattop roof on it.
Since 2012, Peterbilt has come out with an "extended daycab" they use the Ultra roof on this cab (gross).

 

Learn something new everyday. Thanks for a great explanation dirthauler.
