If you could take different components from different truck makes for your perfect truck:
I would take from:
DAF - the engine brake and interior lights
Mercedes - the steering wheel adjustment range
Renault - the power steering and the digital speedometer
Scania - dashboard design and heating controls
Version 1 FH cab on any chassis with a ■■■■■■■ Eaton Rockwell .
XF cab, recaro seats, HVAC system from a Volvo,
I-shift gear box
D16 Engine…
My perfect truck would be the one in my garden I could look at in a morning after turning over, then later use for target practice after winning the lottery, knowing I’ll never have to drive another ■■■■ one…EVER. 
Until then, any combination of different motors, as long as it has loads of cab room to live in, and a decent sound system.
My requirements are simple these days.

What’s your perfect car then Dan?..Cortina mk 3 GT. with a Vaux Firenza body
Similar to Dan, ■■■■■■■■ Prober Gearbox, Rockwell, but an older square style cab (MAN the nearest modern design) but with separate mirrors Daf style, definately not mirrors from Ikea which Volvo fitted to the FH and FM.
Twin 7" round headlights with double dip (all four lamps having dip beam as well as main).
All side marker lights as they once were, red/clear lenses, amber lenses only fitted to indicators.
Box would be the 13 speed Fuller but with column change or failing that Twin Splitter or the old Foden 12 speed box with unequal splits, any of those would keep the steering wheel operatives away
Jake Brake a must, and a secondary blue air line with separate trailer brake handle in the cab.
Dan, that 8 wheeler of yours goes well
111 or 141 with an F90 cab and it’s as simple as that.

Full manual and a bonnet, you’d have it covered Dan.
Bonus points for a Western Star badge.
A 4 series with the retarder on the stalk instead of the dash.

Yes just need space on the roads then ,we’ll here anyway 
There are very many good reasons why you have never been asked to design the truck that you drive. IME they are best left unsaid, mostly because ‘handling the truth’ is not one of your most positive qualities is it?
Having said that, I really would like to meet the bloke that does get to design the trucks we drive. I’d really like to measure his right arm length & to discover how big his feet are. If only he could sit beside me for an average days drive . . . .
I wouldn’t bother.
If I did, then as soon as I got it just to my liking, and clean enough to live in they’d take it off me and send it to another depot, where some nob would take it on, chain smoke in it with the ■■■ ash blowing back onto the bunk, and rip the corners and tail lights out on assorted skips and stillages.
Again.
… the last one I ever step out of.
The perfect truck is very much like the perfect woman. It is not so much how old it is, what it looks like or how it performs. It is how much money it can earn for you that is important.
This will do for me converted to a rigid pulling an A frame drawbar.Dan will hate it.
