    LOL thanks my thoughts exactly. 95% of the work is local within an hour of home on County roads

    Sharp looking truck! I'd have to paint it to match existing company colors etc. I was told to avoid 2004 2008 and 2011 kenworths...? Not to mention it's in Portland so I'd have to bobtail it to Florida to get the box built out. Would there be a specific reason that would make that a better option than what I have cooking now?

    Why is it so cheap?

    Found it looking for heavy front steer autos. Wouldn't have to stretch it. I was just playing around looking. Most anything is going to need modified for your application.

    Fleet truck should have records. Most likely been overhauled and has new liners which fixes many issues with that generation isx.

    OK I get what you are trying to do, but here is what I'm puzzled by is the box weight itself, I've seen huge welding setups that don't weigh that much. I am still trying to figure out what you are doing or what the operation is, you don't have to explain it in an open forum.

    However, here are a couple points to ponder.

    The first is the reason for the double frame, there will be a lot of twisting going on and with a stretch or extension made, that will undoubtedly move your drives back (don't forget you have a limit with the drive shaft), there will be a lot of stress on the frame, and the alignment could suffer, meaning your tires will too.

    The second reason for a double frame is you are carrying a lot of static weight on the chassis, so eventually there will be fatigue going on, the double frame will help with prevent things like cracking in places you never would expect it to happen.

    The weight on the axles are a concern, but I ran a truck for a customer that had an 18k front axle (I recommended for any heavy application) plus a steerable front lift and a rear lift axle. Lift axles are cheap, compared to other solutions. This solves two problems at once, one is dealing with bridge laws, aka road restrictions or weight restrictions, and the other is how the truck can handle 34k load. With that truck, Western Star 5900, I could get on the deck (30 foot long) up to 47k dies sets and the truck handled it well - the truck without a load was 33k.

    Now this brings me to another issue, I absolutely love Macks, I have a lot of them in the fleet, but my HH trucks are all Western Stars because they seem to hold up better. I bought four of them for HH and found they did the work but two gave me fits that I could not afford to deal with, especially when I had customers who depended on moving their stuff. You don't have to stick with one brand or model, I would seriously shop around a little bit just to say you have, you may be lucky to find something that needs a new home.

    AND I have to also ask this, did you actually talk to Mack?

    Not the dealer but the company, they've got a team of consultants there that can help you with the setup of the truck. I've used them before to do my first and second HH trucks.

    Well the long and short of it is I'm loading a truck with all the tools and equipment necessary for rehabilitating manholes.
    Truck 16,151
    Equipment, pumps, hose, tools, chemicals, material, water etc just shy of 18,000
    Van Body 4400
    Full fuel tanks 1,400
    Driver Passenger 450
    Propane tanks, Hydro cement, Sakrete etc 1200
    TOTAL 41,601

    That's all the major components I can think of but not the small parts... measuring tapes, hardhats, tool boxes, hammer drills, sockets, wrenches, pliers, caulk/grout tubes, lunch box, case of pop/water, and about 500 other small trinkets that invariably end up filling the tool shelves. One way or another, they end up full! The guys tell me most of their trucks weigh 46-48,000 lbs. Now that I am thinking this through, I will probably be just fine with what I have. I just might need to be a little more conscientious about letting extra "stuff" accumulate in the truck.

    Say we round up to 43,000 to cover all the small stuff. Balance it for 25% on the FA and 75% on RA. That would be 10,750 FA and 32,250 RA. I think that should be do-able. Might depend on where the axle is....

    This is another guys truck that does the same identical work.

    Who do I talk to at Mack should I call the corporate office? I've been through their website and all the FAQ sections and they refer pretty much everything to the local dealer. I can't afford a new truck as far as ordering and speccing brand new. Plus we'll be lucky to put on 10,000-15,000 miles a year. New doesn't hardly make sense. I know a guy bought one new in 2006; it currently only has like 116,000 miles on it because once you drive to the job the truck just sits there all day.

    Yes the main place should help you with getting in touch of the right group.

    www.macktrucks.com/-/media/files/body-builder/manuals/7-frame.pdf/

    Actually go here, scroll down to the contact us button and send them an email.

    I'm not talking new, I am talking spec'ing it out for you to know what you need to get. They should be able to plug in your needs and spit out what WB, where the axles need to be and so on so you don't guess at it.

    but got to tell you that if you are going to put on 15k a year, maybe going back farther maybe to 2002 would be prudent. I wouldn't worry much about the mileage an existing truck has on it, I would do a dyno and then see if it works.

    The mack you are looking at had 3x the motor that international has. That international weighs next to nothing on steers compared to the mack which means you can transfer some weight to steers on box. An international or other medium duty like that could be picked up for a song and dance.

    Everyone along the way told me to avoid International like the plague?! I agree that it probably doesn't have much motor, it's a Florida rig and that state is flat as a pancake. MN definitely isn't the mountains but we do have decent hills. I'll admit we have extra power with the MP8 but I struggled to find any good reports of newer engines in the 350hp class. I woulda preferred a MP7 but not anything decent available locally. The guys doing this work already said to get at least 350hp. Any less sucks. So yeah that International is obviously out doing the job but maybe underpowered a bit.

    You'd be surprised how few medium dutys are available with tandem axles. Maybe 1 in 50 of then have tandems. And then your stuck with a 250-290hp motor. I looked at some T370's Kenworth but I literally don't physically fit in the cab.
