Saw this in Calgary this week, a 97 model with a select Plus N14 ■■■■■■■ and the wick turned right up, made a lovely noise 
Looks a little cramped inside, but the driver was 6’ 6" and he had plenty of room
The more observant among you will notice it only has 8 stud wheels 
Driver/Owner said it’s a PITA trying to find new rims for it 
On the subject of oilfield trucks, I spotted a late 90s model KW (the one with the side panels that hinge up on the hood) winch truck with a CAT lump for sale in the truck paper, it was up for $170,000, so ■■■■ knows how much a brand new one would be
