    I saw a thread on that somewhere. For sure, that's the ultimate upgrade but it seemed awfully expensive.

    Do all years of m809 have single circuit brakes ? Or are there differences in years?
    I will either find a way, or make one!

    I can't believe you said that!
    15MPH, someone else makes a mistake...a truck like that with no braking just runs over the top of it.
    On the public highway, try explaining that.

    Some people only care about themselves.

    I was looking at the M809 serie and Wiki tells me that they were build until 1982 then the new 5 ton M939 came on. When I googled them I saw some as high as 1985.
    So I am wondering until what year has the M809 series been build?

    You have a pretty good imagination if you think someone who risks his life to rescue an unconscious person trapped in a burning automobile cares only about himself.

    Alright well as some of you I talk to on a social basis know that i was involved in a rear end crash on Tuesday night June 5th. This happened in Mississippi about 50 miles from Memphis. I had my trailer in tow at around 70,000lb GVW. I was driving along at 60/62mph. All lighting on including overhead strobes. I never noticed the Saturn car that hit me. it was a hard enough impact that it threw me into the windshield. At first I thought my ramps had fell down. As I saw sparks in the rear mirrors. I slowed to the side of the road. Applied brakes and went back to the back of the trailer. That is when I noticed the car under the rear of my trailer with it's windshield in my ramps. I checked the driver immediately he was breathing but unconscious. There was a few flames from under my trailer in the engine area. I smelled fuel when I was at the car so I ran back to my truck. put it in gear and tried to pull forward a few feet to see if the car would release. It did not. I returned to the car with the fire extinguisher and tried to put the fire out but to no avail. The wire harness was already smoldering and whatever else that could burn. I then tried to wake the driver up. I reached in and unbuckled his seat belt to try to remove him from the drivers window. He was pinned between the lower seat with his legs and the steering wheel. I hit the seat back lever and the seat reclined some to no avail on removing him. I then started attempting to flag down passing cars. a dozen or so did not stop. I then proceeded to force 3 cars to stop or hit me. This was about 90 seconds from me getting out of my truck the first time till i got someone to stop. They called 911. I then got help from the drivers. I returned to the front of my trailer and grabbed my crowbar and knocked out both rear side windows and the rear window and I climbed into the car thru the back window. I was being yelled at to get out of the car, I tried kicking open the passengers rear door to no avail. and they people there could not pry it out with the crow bar. Others were trying to extinguish the fire with the fire extinguishers as well to no avail. The windshield was on fire as i pulled and pulled on the seat and finally the seatback release broke I guess. I was able to pull him free with several pulls and pulling on his legs. I believe that they were broke. We then exited him from the car thru the drivers window.

    After I got out of the car the by standers took the driver and rendered first aid on him till the EMT's arrived. I then ran to my truck and put it in drive and drug the burning car under my trailer a hundred feet or so to get it away from the people and the driver. I then grabbed more fire extinguishers and tried to put the fire out but it was 12ft tall flames by then. I then used my trailer hydraulic jacks to release it from the truck and let the tongue of the trailer down bringing the rear of the trailer up and being able to separate the two. I hooked the trailer chains to my truck and drug my trailer forward a few feet to get distance. My spare tire, ramp hydraulics lines were burning and both my rear axle trailer tires has busted due to the heat. The EMT's, Fire, and police were all there by then. The driver was air lifted about 10 minutes later as the helicopter for that area was only stationed a few hundred yards away at the air port there. I received some oxygen and minor first aid as my arms were burned and cut up from the glass and heat in the car. Other than that i had several pieces of glass lodged in my skin the next day that had to be removed. I turned all over all information to the highway patrol and given a traffic report number.

    My rear cab camera caught mostly everything on tape from the headlights of the driver for about 8 seconds prior to them disappearing into the back of the trailer and the impact to the fire and extinguish. It is hard to make out on camera really how fast he was going but the impact looks brutal as it slammed my trailer and lifted it from the looks of it.

    As of yesterday afternoon I still did not have a name, age, or condition of the driver. I do know that he was breathing when we got him out of the car and he was when he got in the helicopter. Beyond that I do not know anything else. No report has been submitted yet either by the trooper. The male driver appeared to be in the 18 to 22 yr old range. I am a little uneasy and concerned that I do not know the drivers condition or fate at this point. That is the only thing that is bothering me.

    I revisited the crash scene yesterday with about a 300 yard debris field from impact to final burning spot. There were no skid marks prior to impact. So he never attempted to stop. You see the impact debris and then the marks from being drug and the water mark from antifreeze. Then the burn marks at the final spots. The fire did burn up all my rear LED lighting so it was pretty bright and could be scene as other cars pass me in the video prior to impact. Driver's speed is estimated in the 90 to 100mph range.

    I just hope the driver is alright. The video link i posted and is authorized to be published. It is a private link so it is not listed on public view. Yes it on youtube but it is unlisted.

    I will add. That had i been hit at that speed in the rear of my truck without the trailer the driver would no doubt had died and I would have probably been dead if not severely hurt as that impact would have shoved my rear axles out from under the truck and thrown me off the road or rolled me.

    Right hand corner you see his headlights in the cab glass of the forklift on the trailer at 2:25. Impact at 2:32.
