    Another thing is that the traveling speeds here are allot higher then in Euro. Very few states have a truck speed limit at 55mi/h (90km/h). Many states are at 65 (105), some at 70 (113) and some at 75 (120).
    I usually cruise at 65 (105) for fuel economy purpose. My truck is geared at 1250 rpm @ 65 mi/h. At 75 it's tuning aprox 1500 rpm. ....But loose fuel mileage. Sometimes when I have allot of time and feel like relaxing and letting other people worry about passing maneuvers I drop a full gear to the direct 1:1 in this Eatton Fuller RTLO 20918B trans an move at around 57 mi/h improving my fuel mileage by another aprox 1mi/gal. The more I think about it, the more 57mi/h looks like a really good deal.

    Anywho, with just 2 point cab suspension and spring ride on the front axle, when hitting those bridge transitions at high speeds, feels like I just lost the front wheels and a grenade went off in the cab. It's not the big humps in the road that need to be isolated by the cab suspension, but those high impact sudden shakes caused by the none forgiving and heavy axle suspension.

    What say you?

    There you go again! Back to the horse drawn carriage!

    Maybe you should find a K100 with solid rubber bushing in the front mounts and just a thin rubber pad in the rear latch mounts and spring suspension all around. You'd love that thing! It may just be your "dream come true".

    The coaches have a very long wheelbase compared with tractor truck. Regardless of what kind of axle suspension you have in a tractor truck, you can't prevent the jarring of that cab without an independent cab suspension.
    I guess, you love that seat backrest dislocating your lungs out especially in a short wheelbase COE.
    I remember the MAN F8 of the 1970's well.

    No thanks, I'll pass on that one!

    Agh Lenny c'mon, in fairness! I know you're a smart guy but please! 450k for a couple of bushings and a set of bearings? Coaches operate completely on a different suspension, I've had a couple with air on front and never changed the cab bushings, honestly, who do you know would drive a truck rougher than a pre '94 truck? I certainly wouldn't ! I've driven a frieghtliner and that was way worse than any 80's euro truck!

    Our roads are the worst in Europe! Want to test a suspension ? Come over here! And everyone drives flat out all the time ! I wouldn't drive my 142 around here for a living, I used have a t500, have to be honest, I didn't like it much, the cab was lovely but on our roads , rubbish! Stable but rode like a pig !

    Correct, any modern truck with 4 point has the rear cab suspension low, almost on the bump stops, the front takes all the jarring and vibration, My last 580 had airbags on the front axle and really you could put a mug of coffee on there and it would never spill!

    Oh there's plenty of trucks around here with 3 leaf heavy duty springs , nose pointing skyward and working on general haulage and wondering why they feel solid on the road, on the otherhand I know a few with topline v8's with light 28mm 2 leaf spring wondering why the suspension keeps bottoming out! I won't even say it!

    that is why we opt for highline

    same on every brand large and heavy cabs destroy suspension on our roads , i dont remember any man tgx xxl sold here , because of one reason it is too soft and our roads eat it

    except that highline is 50kg lighter

    use 0.5L fuel less easier to keep cool and warm and quite enough space inside
