Camper towing with my GLE 350

I know this is an old thread, but it’s been so helpful and informative that I had to post my appreciation of everyone’s input on towing with a GLE 350. Thank you all!
I had a 5x12 single axle that wasn’t very heavy and the GLE pulled it ok-ish. Lots of bounce & bucking and stopping was a chore.
I now just bought a 7x18 V-nose dual axle with electric brakes. Following the advice of you all, I hooked up the P3 Brake Controller and added an Andersen W/D hitch setup. I tell you what, that combination make pulling this new trailer SOOOOO much better than the old 5x12 I had. No bouncing/bucking and the adjustable brake gain makes it feel like there’s nothing back there when stopping.
Everyone was giving me crap for pulling a trailer like this with a Mercedes, until they rode with me and found it handles a trailer better than their trucks do. I just laughed at their reactions as they are on the mentality that truck are the only thing that can pull trailers…
Anyways, thanks everyone for the tips and information which created such a great setup and I look forward to many miles of towing!




I did tow a lot with older W163 and now with W166 and never needed them.
Also did you hook up brake controller? How did you find harness?
I found the brake controller adaptor for the P3 on Amazon and plugged it into the factory harness that’s tucked up under the knee panel on the drivers side. If you have the factory hitch installed, you’ll see a green plug tucked up there.

Unfrtunatelly most of the links in the thread don't work anymore.
I think buying pegs and wire at dealer and assembling the harness is still valid, but I'd rather buy something ready to use.
