    Awesome!! It is so worth the drive to buy a truck from him the detail in his specifications are absolutely amazing definitely way better than Fitzgerald.

    Those legendary colors are amazing, I changed my color Choice from the Monster Energy green to the legendary metallic blue......

    I love the metal flake in the legendary series it makes it really look awesome!


    You're going to have one heck of a sweet-looking truck!

    No - a dd15 in a Cascadia with a dt12 direct. Nothing really special for specs.

    I've been asking everyone I see with an X15 how they like it, and so far this thread was the only negative feedback I've heard.
    The most one guy had was 87K on his, and he said he's had 0 issues.

    Too bad we can’t get a 389 with a DD15.

    Fyi, I've had ifta quarters in low 10s before with the XE-455 Specd volvo with downspeed drivetrain.
    1100rpm@63, 1150rpm@65 , 1200rpm@68mph

    The XE software gives the engine incredible low rpm grunt.

    I'm not looking for another plastic aero truck even though the 16' Volvo has done outstanding for me....

    I'd be curios what the differences are between the X15 performance series and the Economy series...... Compression ratio higher on economy series maybe? Different software and cam profile maybe?

    Yeah I really wanted a Glider with a Cummins red top N14+ but the con artists at the glider builders wanted WAY WAY too much money for them.


    The new DD15 Detroit has a ton of low end grunt now! Pretty amazing what Detroit has done to change it's low rpm power curve !

    So the first one (Demo unit) in a 2018 LT, started pouring white smoke and lights like crazy pulling Kicking Horse Hill, just after golden. The dealer came and got it, and we never seen it again (Company took possession of the X15 LT's shortly after).

    Those X15's LT's bankrupted the company I was working for, so I just switched to an LTL company this past week. Got assigned a REALLY NICE 2019 LT with A26. First #### load, lost the bunk heater and rear EPU/HVAC system first night in the truck. Then around Moose Jaw (3800kms on the clock) it lights up like an Xmas tree. So I pullover and call breakdown, they do remote diagnostics, tell me I can finish the run to Calgary and drop at the dealer Good Friday. Just got off the phone with them, truck needs 6 injectors, a wiring harness, new EPU/Bunk heater and tons of other #### 4300kms.....FML

    International is a brand, I would recommend TOO ####ING NO ONE!!!!!!

    If you don't mind sharing how much do Peterbilt Steve's 389 cost? Or a ball park figure would be appreciated. I've watched a lot of his YouTube videos, nice trucks for sure.
