I am a newbie here...just bought my 1st Mercedes (2001 ML430)...the Towball is missing & I am trying to get a replacement...I think it was originally factory fitted but attach a screenshot of the fitting if anyone can help.
The towbar is the type where the towball clips into place via a pin fitting & isnt attached to a hitch plate...I am pretty sure its original manufacturers fit & not aftermarket.....similar to below...sticker mentions "Oris".....not sure if they are the manufacturers..

ORIS supplied the factory on pre-facelift cars. Try eBay, your local MB main dealer parts counter (ask for a discount) and contact ORIS themselves.
It's highly likely that ORIS only make one type of detachable so even if you find one listed on eBay for a different model, it may be still worth a punt if it's cheap enough. If you do then I'd suggest going for one from another full fat SUV in case the hitch weight ratings differ - other bg SUVs will be higher. I think yours will be rated for 135kg.
If you open up the right hand compartment in the boot, there will be a cut out in black foam for the detachable towbar head. (behind the CD changer if you have a swing out CDC in there)
Thus, if you get a Oris one (like the original) it will stow away nicely in there when not in use
