weight distribution hitch ...I'm confused.

Talked with a lot of reps and manufactures today. What I gleened is they all have differing answers. Going with a WHD hitch for this trip if it doesn't work out then a new heavier recover hitch will be installed. Thanks for all your help. Would have gone with straight ball and hitch towing as many suggested but I don't think I would be legal and libality would be outrageous.

Your tounge weight may be less due to the way these trailers are designed. The car usually sits in the rear, most of the weight being right over the wheels and to the rear of the wheels.

Thanks for all your answers, I am taking it all in and have learned a bunch.

Freightliner said to call Fleetwood. Fleetwood did the math, then supplied and installed the receiver. Freightliner considers it aftermarket install. The more I look into it the less scence it makes. The purpose of WDH is to level the ride, thereby distributing the load evenly. It does not reduce the tongue weight, if anything it appears to increases it. If the air bags level the load then why the need for WHD to level the load. From a laymans position the WDH does not reduce any stress on the frame any more than the leveling done by the airbags. The axle weights are with in spec so ?????? I"ll see what Fleetwood says Monday.

I'm hoping Freightliner will provide helpful info. Since the hitch is so far behind the rear wheels it may not be as simple as an upgraded receiver.

With an 800 pound tongue weight and that hitch it seems like you would need a WDH. However, I think using one is silly. Just upgrade the receiver to one that can handle the tongue weight without a WDH, they are available.
With a tow vehicle that huge there's no reason you can't put 800 pounds on the hitch.

Trailer weighs 3680 lbs the car is 4,130 lbs. Tounge weight of trailer is 400 lbs. So tounge weight loaded with car would be around 800 lbs. I am well below the 1k/10k the receiver hitch WDH rating.

Where to start....I just bought an enclosed car hauler 10,000 lb.

I assume the gvwr is 10,000 and the car+trailer will be somewhat less. On thing to watch is the loaded tongue weight.

It looks like I need weight distribution hitch or do I since the air ride is self leveling or is there stress on the frame I am overlooking? Wouldn't the two systems fight each other? How could I adjust tension if MH keeps leveling automatically?

I assume the 10K/1K rating is for the receiver. If the receiver is OEM from Freightliner maybe you can ask them about it. The WD hitch will still distribute the load even it it does not raise the rear and lower the front of the tow vehicle due to the air bags.

I'm not sure how you would adjust the hitch though. Maybe you could go on level ground and turn off the auto level adjustments (engine off?) and use the regular process for adjusting the hitch? If you can get help from Freightliner I would ask them what procedure to use for setting the tension on the bars too....

Don't forget to verify the loaded tongue weight at some point...

I am currently towing a 37' race car trailer that weighs 14,800# with 40' diesel pusher with no problem. Yes, you should use a w/d hitch. Feel free to p-m me if i could be of any help.

With those specs you cannot tow that trailer period. If the MH can handle a 10K flat tow and a 500# tongue it means that the frame is not setup to go beyond that. A WDH isn't an option. IMHO you can't get there from here....
