I was also wondering how he gets away with it, I bet he has that prepass device in the truck and they give him the green light on weigh station bypass. I bet he only drives at night too, the video was taken at night. Once he drives past a weigh station or a dot inspector stops through where he is parked while sleeping/on break he is gonna be sent to Guantanamo for the state of that truck. I think I heard him say he drives at 70 mph, I never take a risk with steer tires, and he states that he is always under there pre tripping and inspecting the truck, I would hate to see what neglect looks like by him. I need more videos from this guy. I need to get an update. I would like an entire series just him sneaking past weigh stations, in the dark of night. Voice-over by the guy who narrates deadliest catch. "American Outlaw Truckers".

I would say, they are both very old trucks. Make sure they have maintenance logs to come along with that 27,000 asking price, that is really high especially for today's trucks, 450k is alot of miles, if it has been neglected. At the same time 10,000 can turn into 27,000 really quickly, whichever one is going to be more reliable would be my advice. If there is no service history for the e tech and the 10,000 dollar truck looks like a real turd keep searching, the truck market is on fire right now, tons of trucks to go around, make a good decision because profitability is difficult right now.

Fellas it is a long loooong video, I personally haven't finished it. This Mack has seen better days, but the video is good. He had me entertained, and there are some tidbits of information here and there.

Those have a very classy look to them. 10/10, thank you for posting the rims, I wish I could be around to admire that truck in person, what a truck. I would freak out if I saw that rig parked at a shipper.

Behold, the ultimate form of the ultraliner. This is exactly what the guys had in mind at the mack headquarters when they cooked this baby up.

I did some digging around, and I believe you. I am going to go check one out and I will post up some photos. I have to satiate the ultraline bug i have.

They have delusions of grandeur. You're absolutely right about that! Now I have a question. Regarding the frame of that 653 with cat opposed to the 613 or 633 with cummins, we're they all the same dimensions or did the frame get wider with the nunber variations? And is the v8 MH still a 613? Or did it have a different code?

I was wondering what these rims are made of, they look like unpolished aluminum, but I know that can't be right, has anyone seen em up close?

Thats nice, I like that, thank you. Do you by chance have also the EM7 chart in that book? I was trying to draw up comparison of what these engines offer as far as torque values and when it throws it on/how long it lasts for.

I would like to see the graph for 1992 EM7/E7, please. I have been digging around, hunting stuff down, would be really nice if you could help me. Here is something i found for a bit newer engine, for the hell of it.

Does anyone have the Mack EM7 dynamometers for the VMAC years? I have been turning over some stones to find this information, all I can find is this, and in the past I have found some really flat torque graphs that were displaying less of a drop off, where as in both of these EM7 and EM6 have very similar characteristics with the torque falling off towards the higher end of the RPMs em6300.pdf

Thats really cool, you went to some pretty extraordinary lengths to get that economy. I have never heard of two speeds on the rears, was this something you would try 4.10 then 5.63 in order to determine which was better on fuel, or one ratio per axle say forward 4.10 rear 5.63? I run cats eyes pressure monitors on my rears, takes the guess work out of thumping the tires and saves me a little time to hit em with a pressure gauge, that gave me piece of mind when i was doing my pre-trips. I never permitted airleaks myself, but I couldnt say for sure what the air compressor sounds like when it is going down the road. I admire how you try to minimize any parasitic loss that is easily tenable, I bet theres a lot of money lost in trucking just from that alone overall in trucking. I have been looking into a solution to idling, I didn't idle unless the temperature got below freezing, or I was at risk of heat stroke because I didn't want to foul up my emissions system, but now that I am getting back into it, I want to get an APU, I feel like it would recoup the value with quality of life improvement, cost of maintenance and the value of fuel savings. I ran a harbor freight predator gas generator for a little while. I study the effects of rolling resistance and take preventative measures to save my pocketbook but sometimes it just doesn't pay off. I lost my ass on some drive tires, they were supposed to be good RR tires made in USA 500 a piece and I lost an MPG overall when I had em put on. They were slightly aggressive tread pattern because I do some occasional offroad but damn, going from 7.5 to 6.8 mpg was a lot to absorb with 4 dollar fuel, on top of the 5000 dollars I paid for the tires.

Hardly anything left of the truck, entire thing has been eaten away by rust and time, no instrument cluster, nothing in the interior, but the engine runs... They got their priorities in order. Throw a milk crate on the floor and you can drive it home today. It would look really with some minor touch ups and a wooden flatbed.

What kind of throttle discipline do you have, what speed are you driving to achieve this 6.5mpg? regardless, 6.5 mpg with 80k is impressive, i had an isx15 and I was getting that MPG out west on I40 Memphis to Los Angeles, I drove like I had an egg under my foot, the truck would not give me good MPG, I think it was the 10 speed and 2.64 rears, I could squeeze out some serious MPGs if I was loaded light, hit 9mpg a couple times and I was super happy about it. Regardless, I am hearing you out with this mechanical idea. It seems crazy, but it also sounds extremely reasonable considering everything is getting old that has pre 2004 electronics. I would need some advice if I were to go that route, what kind of setup would you recommend? I am thinking big cam was king as far as cost of ownership goes, repairs fuel efficiency and reliability. If I could do 6mpg on average, I would be alright. That would certainly make up for the yearly 20,000 repair bill on the emissions system with the tow and loss of profits from downtime.

Facebook For the sake of staying true to the MH613 namesake of the post, I present, a running Ultraliner for sale $3000. I guess I was overpaying possibly. Can't believe how cheap these go for, it blows my mind. You can't even buy a 2001 nissan altima/honda civic for that price!
