The M269/270 have both connectors. Also has the standard king pin which is incompatible with the M920, but I think you know that already.

Everyone has a m270 and I never find one.. get picks of it. Like to see how one looks on a 920.

NDT going to use a 2 to 3.5 adapter to run it home . So your saying the M270 can be 12v or 24 V ?

Jdgreen, I bought it from a SS member Jwaller. Going to pick it up next weekend. Ill take some pictures. It wont look like a M270 for long. Going to add ramps and maybe a short beaver ( I need to find out what the law is on the length I can get away with ) and use it to haul my equipment. Was on Fort Meade on Friday and Saw 2 really nice setups the first was a 900 series like a M925 but instead of a bed it had a 5th wheel and it had a M270 attached to it . It had Tags that said US Government. The second rig was what looked to be a F850 with 6 doors and a extended cab with what looked to be either a flatbed or a rollback bed on it ! It was SWEET !!

Every 12T M270 I ever saw was straight 24v lights. However, units in the field were known to add a 12 volt circut ala M127. What is yours ?

Also the floor is 40' lon g plus the gooseneck out front so it is really a 48' trailer out of the box. Max length for one unit is 53' I believe.

Well I have 2 e mails from him, 1 saying 24v but the 1 today says 12V so lets go with that . Also after talking to Soni I may have to remove my ramps and relocate my 5th wheel more to the rear. He say on a M915 there is about a foot more room than on a M920.

My M270 came with 12 volt and 24 volt electrical systems.

Hey DaveP is that on a M819 ?

It is.

Wow what a nice looking truck ! It does look aweful close on the back side. I'm willing to bet I will have to relocate my 5th wheel on the 920.

The M270 was designed for the M919.

I agree you will have to remove the spacer, ditch the ramps and slide the 5th wheel back to clear the trailer.

 

[DaveP]

I dont have a M920 yet to compare to. but the M819 has a lot more frame behind the 5th wheel than the standard tractor.

heres a shot of the clearance between the M270 and the M819

 

[R Racing]

Well looks like my work is cut out for me, LOL

 

[R Racing]

WOW That is close !! I bet that makes much better turns being it kicks the trailer out during the turn.

 

[DaveP]

Here is the clearance hooked to the XM818

this is not close at all.
lots of room. even for off road operation. keep in mind that it cant ever get closer-- other than on severe changes in elevation. and if anyone will find out the limits it will probly be me. in order to get the rear of the tractor frame anywhere near the front of the trailer i would almost have to drop the front of the truck off a cliff.

I was thinking in a turn when the drivers rear tire swings under to the passanger side and visa a versa. you know the possible pinch points.It looks like you have room. But in my case I believe it would hit.

 

[DaveP]

here is the data plate on the M270. this will give you dimensions to compare to your tractor.
just use a tape and hold it in the center of the 5th wheel and swing it around.
