Towing with the ML
I am considering buying a boat with a trailer...the trailer is a single axle with disk brakes on it.
Question, once I install the MB tow hitch, will the ML power the brakes on the trailer too? I know, it will do the brake lights, but don't know, if the brakes get hooked too..does anybody know?

If the brakes are electric, you can wire the electric controller to the trailer harness in the rear and power will be supplied thru that large socket plug in the rear. I installed a Prodigy unit on my ML.

Also, what is the best place to get a tow hitch...
Some time back, I had seen some advertised on eBay, but I would be a bit weary of buying any after market stuff especially for something that critical...is there any other place to consider besides the dealer?

The (MB) wiring harness is easy to plug in and you will probably need to use a 7 wire to 4 wire converter (if that is what the boat trailer uses.) 4 wires would also indicate surge brakes (or no brakes).

You will have no promblem. The ML hitch is a class 3. The vehicle is rated for 5,000 lbs. Normally boat trailers have surge brakes. No electrical connection will be needed other than the normal brake light / turnsignal lights.

I just got educated by the boat dealer..
Yes, when he said disk brakes, he meant surge brakes...so I should be fine...and the boat weighs in at 2600 lbs dry weight with the trailer so my ML320 should be able to tow it rather easily...
