Oh, Lord... yes, I am follically challenged and I'm sure he had a lot to say. I suppose it's good that I was biting my tongue the entire time I was there. Those people were, how can I put it... defensively offensive. If they hadn't mistakenly told me that they could do the work (new employee, apparently), I wouldn't have wasted my time on them.

I'm going to be putting my hitch on today or tomorrow (Clear Creek RV Park, run by the city of Golden, is amazing, and that's where I'm staying while I work out the kinks in our new 27FB -- figured I'd better stay near the dealer for a bit, and that has turned out to be a good thing).

I forgot to add: I think I found one! Two, actually -- real, bonafide fabricators, one of whom makes hitches for real trucks (big industrial rigs), and aren't afraid to do Andy's hitch reinforcement after looking at the pics I sent them from earlier in this thread. Finally!

That said, I agree that Kim is probably not going to run into that with their 19'. I'd still talk to Andy, though.
Just to be clear, the GL/ML hitch specifically supports WDH. The issues being reported here and there on hitch bending due to WDH use, is happening ONLY when the hitch is massively overloaded (say your tongue weight is > 1000#). This is not due to a flaw with the hitch design, rather due to ignoring the specs.

There is an issue with the overall specification for hitches in North America, where the SAE underestimated the torque resistance required when using weight distribution when setting their original standards. It's eloquently explained in this VAP podcast by Andy Thompson and underlines why he has a business in strengthening and fabricating hitches. My apologies if I've infringed any copyrights here, I will gladly take the link down if required.

It's quite a long podcast and comes with a disclaimer at the beginning, which made me smile. Anyway, it's excellent listening if you're interested in hitches and towing

MPG return.

OK, I have a 20 ft FC being pulled by a Tahoe gas engine. I get 17 mpg when not pulling and it goes down to 12 when I am pulling the Airstream.
I thought if I went up to Diesel my return would be better. I have a chance of a 2012 ML Bluetec Diesel and specs say on highway the return is around 29 mpg. Looking at some posts here you boy's are only getting 15 mpg.
Having had many diesels in Europe that returned between 50 and 65 mpg, then having two big trucks that only returned around 17 mpg here in the USA, diesels tend not to loose mpg when pulling, my Chevy 2500 and Ford 250 lost nothing at all when pulling. I know these are different animals but I see no point in lashing out the cash for a Bluetec if the mpg return is rubbish. I had expected to see you talking about a drop from 29 mpg down to 23 mpg when pulling.
So please what is the deal here with this Bluetec, 3 mpg increase over the Tahoe does not convince me of going diesel again.
Thanks for the replying in advance.

Jmpgino - I haven't pulled my Airstream with my Benz yet, but will reply again in a week when I make my way from Denver back to Des Moines. I've had my 2014 GL Bluetec for about 2 months and on a recent trip to Chicago towing a smaller two wheel trailer with a golf cart, I didn't lose any MPG...still maintained 28mpg entire trip. I know I'll lose more pulling the AS, but I would be doubtful I drop below 20. We shall see. I'll update and let you know next week.

Thank you for the reply young lady, I await the numbers. Drive with care.

Cheers

Is there any official information on WDH limits? My '13 hitch data placard does not show anything about it. Mikapen, what does yours show?

On our '12 GL, per the hitch decal, the max tongue weight with/without WDH is 600#.

So... for instance, if you have 770 lb hitch, you just need to transfer 170 lbs+ forward?

My hitch data plate, on our 2010 ML is attached. Note the part number starts with A164....
For ML, it shows 7200 Max Trailer weight and 576 Max Tongue Weight, same ratings for "Weight Distribution" as "Weight Carrying."
Note that 576 is exactly 8% of the trailer weight. Same for the GL ratings.
As has been discussed elsewhere in this thread or forum, Europeans seem to be OK with 8%, and that may be all the science that is used to arrive at the 576 lb number.

Does that mean that if I am OK with 12%, then the number is 864? Probably not.
Does that mean that our ML's are stable with only 8% tongue weight? I dunno, but we're very stable at 10-11%.

Also notice that there is a diagram of ball height ranges and max distance from hitch hole to ball.

It looks like you are a good gas-mileage driver. From what you are saying, I'd bet you can add 8 mpg to all your figures.

Here is my story:
Pulling our (SOB) 27' Lance on a 4000 mile trip, our average was 15.5, verified by hand. That included stop'n'go in Chicago for hours. Our worst on that trip, into 40 mph quartering headwind, gusts to 60 and semi's on their sides, was 12 (slowed to 50 mph). Our highest complete 25 gal tank was 22. (That's a day and a half on a tank!) At a steady 62 mph on flat ground, no wind, we get about 17-18 mpg.

If I really go for fuel economy and stay under 57 mph, we do see 19 - 25 mpg. Our Lance is nowhere near as aerodynamic as an Airstream. Over 68 and we're in 15 mpg territory. I don't drive 70 very often.

Not towing, our overall fuel economy is 26 mpg. Saw 39 over 45 miles last weekend, 45 mph, moderately hilly. Low 20's in town if I'm late for something. A similar 4000 mile trip netted 29.7.

But the BIG advantage is how much more authority your engine will have over your trailer, and how little your transmission will shift.
It's like they posted a "No Hunting" sign on your transmission!

The question is what does the Lance weigh, dry I am about 3,800 lbs. I met a bloke who had something 27 long and topped the scales at 11,500 lbs, hell I would have the wife out pushing that mother up hills........

As completed at the factory, our Lance weighed in at 4561 lbs. Ready for travel with full water tank and fridge, we're about 5500 lbs.
