Two interesting things that have been reported on and verified are the captain driving this boat when it collided with the bridge is Ukranian. Also there is footage of the Dali colliding with docks at the port in Antwerp Belgium in 2016. Not sure if it was the same crew or not. I'm guessing not.

If Stellantis / Fiat/ Dodge / Ram or whatever they are called these days had any sense they would just replace their mediocre Hemi with one of these as the gas engine option in their 2500s and up. They already have the exclusive agreement with Cummins for light duty diesels. From looking at the performance specs my guess is this thing would run circles around the 6.4 Hemi for towing and heavy duty pickup work and would probably be more efficient while doing it. The two major drawbacks I see for this as a base gas engine would be weight and cost. This thing is probably a few hundred pounds heavier than a Hemi v8

Is that the exhaust coming out behind the rear fender like a pickup?

Sounds like you would be good to go then. Like I said if its already converted to 22" hubs to run 24.5" tubeless rims then I don't see a problem. There should be a hub pilot hub that crosses to that spoke hub's dimensions I would think. Maybe you would run into weight rating issues. Maybe hub pilot isn't rated for that much weight? Just looking at the two styles its easy to see how spoke hubs can safely bear a lot more weight than hubs supported by wheel studs. I dunno. I would just call the experts and ask the question. Also what is the truck used for? Depending on the application, spokes provide a lot of benefits in my opinion. And being that they are already converted to 24.5" tubeless hubs/wheels I'd say you probably in the best position already.....

I don't know if I've ever seen 58k rears with tubeless rims/tires. Only 11.00-24 and 12.00-24 tube type tires. Its an interesting question if the wheel ends can be converted to 22" hubs to run 24.5 tubeless tires. Someone on here will probably know if its possible to do, however, I would call Barry at Watts Mack and ask the question. If it is possible he will be able to give you all the correct part numbers for the hubs, bearings (if necessary), seals, etc. My buddy did a conversion of 38k Mack spoke hubs to hub pilot and Barry told him everything that was needed and gave him all the part numbers in only a few minutes. Being the truck is a 1998 I don't think finding the information will be much of an issue.

Here is some more pics.

If you look closely at the emblems they do say F700. Plus it has a vendor engine (Detroit 8V71) which is typically in 700 series chassis.

The engine serial number is stamped into a ledge in the engine block casting just above the water pump housing on the front right.

Saw this on Marketplace. 1965 F700 with V8 Detroit. Pretty unique truck. Looks very complete and very nice shape for the age and almost a steal price wise. No affiliation. Thought some here might be interested. https://www.facebook.com/marketplace/item/781622967179524/?ref=search&referral_code=null&referral_story_type=post

Most times they say don’t run 5th with the axle in low is because it’s not a progressive shift from 4th over. With 5th being overdrive and depending on the two ratios in the rear it actually makes 5th under slightly lower than 4th over. At least that’s the way it was on ford and Chevy medium duty trucks with Eaton two speed rears. If 5th was direct then 5th under was a progressive shift from 4th over.

I'm sure @Joey Mack will be along shortly. Could you look up the part numbers through PAI and see if they are the same part? I guess even if they were the same part they might have different numbers since they were different engine families....good luck

CNN not the greatest source IMO but this article isn't really political and is pretty insightful as to how maritime insurance works. Pretty interesting. Who ends up holding the bag for the Baltimore bridge collapse? | CNN Business

As far as I'm concerned the public water supply anywhere is always under threat. I can't believe it has never really happened (that I know of), or happen frequently enough to hear about, but poisoning a public water supply is incredibly easy if you possess a 6th grade knowledge of plumbing. Any home connected could be made into a contamination point. Shut off service valve where water service line enters home. Remove backflow preventer if one exists. Install a hose bib. Connect a chemical feed pump with enough head pressure to overcome the static pressure at the street. Start pumping some toxic chemical into the system. Once the chemical gets into the main lines it would be game over. Depending on the system particulars and time of day an attacker could probably pump 1000s of gallons of toxin into the system before anyone realized there was a problem. Depending on the system It would be incredibly hard to if not impossible to determine the location where the contaminants were introduced. If it happened on a large enough scale in enough locations society would instantly turn on public water supply. It would be mass chaos. I worked in the industry for many years and can't believe how fundamentally easy it is to poison public water and also how cavalier system operators are about how easy the systems are to breech.

My guess is the US taxpayer will foot the bill and then the US government will try to get reimbursed from insurance / bonding companies. Again guessing here...the demo and reconstruction will start almost immediately like when the interstate bridge collapsed in Philly from that tanker fire and they rebuilt it in like 2 weeks or something. The insurance company will want to drag its feet and investigate and litigate and procrastinate to try and pass blame or hold some other entity responsible. Leaders here will find that unacceptable and at least get started with our own money.

My guess is a 3408 is about 1,000 pounds heavier than an E6.

Long gone. The blue one got sold for parts and its major components may have lived on. The DM800 got scrapped and probably sent to China to be turned into some worthless trinkets that serve no real purpose. Its sad I couldn't find any takers at scrap price. The cost of shipping a 19,000 pound back then was very expensive. That was in the 2020-2022 timeframe when the Covid supply chain BS had everything screwed up and the cost of shipping anything was crazy. I saved the ignition switch out of it that had a matching Mack bulldog key. That is all that's left of it....

Do you know what cubic inch V6 it has? That engine family is crazy interesting and has a lot of other unique engines based off of it.

Those frame channels look way bigger than any I have ever seen on a regular loadstar. I always thought they were some of the best styled trucks of the time. That cab and front clip design is timeless.

Like I said I have two of them. And yea they are different from the one on this superliner. Attached are some pictures of my newer one. It’s an 88 or 89 model. It’s in near perfect condition. Just needs painted. My other one is from the early 1970s and is a little different. The overall shape and design are the same but it has windows on each side is the main difference.

Does Rest Rite sound familiar? They were very popular on with operators of Mack trucks before Mack produced their own integral unit. They were manufactured not far from me. I have an interest in them and own two of them. I'm actually just curious. I can't tell for sure but it closely resembles one. The black paint and picture resolution make it hard to pick up on any fine details. Thanks.

Yes same. Computer controlled and clutch actuated with air pressure. Detroit DT12 is another one

Does anybody know what make of sleeper it is? I never looked at the original listing.

I guess now that I think about it I'm not sure if the grade gripper is for trucks with a manual transmission or if its specific only to trucks with the M-Drive automated manual. I don't really know. It has to be a part of the M-Drive system so the air actuated clutch can engage smoothly without the truck rolling backwards. Perhaps its also a part of a manual setup now as well. Somebody more familiar with the new stuff will probably know. My passenger car with 5 speed manual has the same technology and its super annoying if you actually know how to drive a manual....

It is a new age nanny device to help "drivers" who don't really know how to drive a manual transmission actually drive a manual transmission. It keeps air pressure applied to the service brakes for a period of 2-3 seconds after releasing the foot valve. This is supposed to give someone time to get their right foot over to the throttle and start giving the truck fuel and not roll backwards if stopped on an incline. Hence the name "grade gripper" 🙄

A 690S is Vocational spec with the Maxidyne version of the E6/E7. It will be either 250, 275, or 300 horsepower Maxidyne. And generally have a 6,7, or 8 speed vocational transmission, which is basically just a regular 5 speed with either 1, 2, or 3 off road creeper gears. Paired with really deep rears. All three of those transmissions have the 0.6:1 overdrive in them so there is that really annoying gap between 4th (direct) and 5th gear. 4th gear your maxed out at 40/45 mph and 5th gear it takes off like a rocket ship and has poor gradeability. They are actually a great setup for certain types of work and terrain. I imagine in Oklahoma where its all flat would be a great set up.
