Default Part number for 7 way plug bracket

Hello all
Looking to see if any one might know what the part number is from Mercedes for the metal boxed bracket that the 7 way trailer harness attaches to on the tow receiver. The newer Interstates are coming with a new bracket that mounts the bracket flush with the receiver so a cover plate can conceal everything when not in use. Thus far My local MB dealers have been unable to identify the new bracket. Thank you.

AirstreamnwDale,
Can you find a VIN # for one of the new Interstates?
Have you had them run their search on epc.startekinfo and or WIS with a VIN# that actually has the bracket you are looking for?
Are you wanting to take the angled bracket off and install the new flush mount bracket?
Is there a photo anywhere of the new bracket?
Roger

You may be looking for items # 30 in the attached EPC picture. But I can't get the Part Number from EPC because it says it is not applicable to my VIN for a 2013 Interstate.

Nice to know Airstream switched to a plug that doesn't hang down like mine. My Interstate is the 24 foot long body Sprinter and the plug bracket is the low point in back. I've nearly scraped it off several times. I think I can fabricate one like the diagram to eliminate problem. But it would be nicer to just get the MB p/n.

Cheers,

It's a little late tonight (2 AM) but I can get you the MB Part number for that bracket.
The drawing you provided has the AUS hitch listed in it, which threw me off.
I will look tomorrow evening. If I don't get back to you by sometime tomorrow evening, send me
a PM to remind me.
I've had that bracket on my last 4 NCV3 Sprinters and I have VINs for all of them so no problem looking in
epc.startekinfo.
I originally thought you were looking for a straight bracket, but it seems you want the angled bracket.
Roger

Sadly that exploded view is of the angled bracket part number A 906 310 67 09. But its not the one I am looking to replace. Airstream has not relocated the plug, It still hangs down under the receiver just not at an angle. I will try using the vin in the link you mentioned, I had not heard of it before. I will post what information I can find.

Thanks Roger,
Looks like Dale has the p/n of bracket I was referring to (A 906 310 67 09).

The Trailer Hitch (item 20) in picture above is p/n: A 906 310 12 95

This item is the SA Code Q24: NAFTA TRAILER CROSSMEMBER, TOWING CAPACITY 5000LBS

I was hoping the angle bracket would fit under the cover that Airstream installs over the hitch like the first attached photo in black. But it doesn't look like it and that is not what Airstream has done to correct issue. That MB bracket (A 906 310 67 09) looks like the one Airstream was using on the pre-2013 Interstates like the attached photo in silver.

It's my guess that the Airstream installed bracket is a custom item they add that is not a MB part. I've cut mine down and re-welded it so it's now just above the skid bars under the hitch.

Mike,
I guess your RV are built on the 170" EXTENDED cargo Sprinter...right?
It's hard to see how you could drag the rear end, but I see the wheels in the black photo, so I guess it must be a problem.
You could cut a hole in the fiberglass (??) valence and install the angle bracket but you would have to remove quite a bit of it
on the LH side.
If you need any other part number, let me know!
Hope this helps,
Roger

Thanks Roger,
Yes -- the Interstate Extended Lounge model is built on a 170" WB, EXTENDED Cargo Sprinter.

It's pretty easy to scape those skids on the trailer hitch with the long overhang of the extended body. They are only about 14" from the ground. I added sacrificial wood blocks to mine might try to add some wheels/rollers that are common RV accessories. I'm on my second set of wood blocks now.

I appreciate your quick response. I've followed many of your posts on this forum and you speak with a voice of authority.

Cheers,
