Default Towing???

Hi everybody, I have a 2011 Mercedes sprinter and a 8,000 lbs travel trailer.
The trailer is 8,000 lbs DRY!, so about 9,000 with water and diesel for the generator.
The towing capacity on my sprinter is 5,000 lbs.
We drove it for 60 miles on rural roads and it was fine going about 55 mph.
We are planning a road-trip through the Appalachian mountains, what I need to know is has anybody else attempted this, will my sprinter be able to pull it up those mountains, and will I damage the truck.

-Thanks

You might damage the van's structure underneath, throw out alignment, over-work your differential+ transmission+ turbo+ brakes, and risk being at fault for an overloaded van in an accident, risk fines for not obtaining/being unable to obtain state commercial permits (over 14,000# total weight) etc etc.
It has been done without damage, 1 member towed 14000# trailer slowly to the dump.
It is not recommended, but solely for the high risk taker, MB will not fix under warranty, they've got the tools and specs to test for overloading.

Who the hell cares about the damn vehicle or trailer...

You sir..are a reckless and dangerous moron.... has it occurred to you that not only do you risk killing yourself, that you might in fact kill others?

Hey, folks... at least he *asked*.

Florida's kinda flat... the effect of an overweight trailer won't really appear until you get into odd situations...
such as coasting downhill and finding the trailer trying to pass you.
It starts swerving side-to-side behind you, pulling the tail of the Sprinter side to side.
You just know that applying the Sprinter brakes before the trailer brakes is only going to make it worse....

--dick (learned (and somehow survived) through experience 40 years ago.. and no brakes on the trailer...)

Hi sprintersneedsmoke,
Is your Sprinter a single rear wheel on each side (2500) or a dual wheels on
each side (3500)?
If you bought the MB installed trailer towing package, in your 2011, you also
will have the trailer stability module.
What is the wheelbase on your Sprinter? Longer wheelbase Sprinters (not the extended rear) have higher towing
capacities.
If you have a short rear end 3500 Sprinter, your towing capacity (with the factory
installed hitch and an electronic brake controller (from the aftermarket)) your towing capacity is actually 7,500 lbs.
If you purchase a weight distributing hitch, you can increase that to around 10,000 lbs.
The Sprinter will tow that weight, if you drive it correctly....manaully downshifting whenever
the % engine LOaD gets > 85%.
MIght have to limit your speed to around 60-65 mph, but with a huge trailer on the back
that will help you with the mileage alot.
You would need a ScanGauge II/UltraGauge EM/DashDAQ to be able to monitor things like the
%engine LOaD, coolant termperature.
Essentially, I agree with the others if you have a 2500 Sprinter with no electronic trailer stability control or electric brake controller.
You would be very unwise to attempt to tow something that large with the smaller lighter
Sprinters.
If you have a 3500 with Dual Rear Wheels, it's alot more doable as you have a better gear ratio for towing (4.187).
Hope this helps,
Roger

I've towed quite a bit with a Sprinter.... and with more weight than the incredibly intelligent engineers (no- their lawyers) suggested.

Unless things have changed, buying a weight distribution system will NOT change how much the lawyers at MB think you can tow. The factory hitch is set up for 500/5000 going much over that wouldn't be real bright. Curtis used to have, don't know if they still do, a class 4 hitch 1,200/12,000.

I wouldn't go THAT over weight..... the truck can probably deal with it but the computer at some point won't.

The trailer I used to pull with my Sprinter 2004/2500 was sold to a couple we knew who was towing it with an E350.... I used ACTIVE sway bars they used NO sway bars - it is now in the dump.... she rolled it (her second) the ol semi passed, got it going back and forth - NO ONE IS GOING TO SAVE THAT!

Yeh bigger truck would be better (or lighter trailer). And you do know that ALL OEM trailer tires are junk right?

I can't begin to describe the feeling you get when you see the trailer appear in your side-view mirror... flying through the air, landing on only its outer wheel, squashing its spring, then rebounding up and disappearing out-of-sight as it leaps up and heads back over towards the passenger's side...
