Using that logic, I should get 750# WDH bars. Since the GVWR of the camper is 5212#. So my next question is will the 1200# WDH bars be too stiff?

I don't think the 1200# bars are an issue. You would need 100# bars for the 750# tongue as 800# would be to close considering how much your tongue weight could change with one or two quads on the front. I am running 1000# (what the dealer had when I picked up the trailer) bars on my Vibe 6501 and it only has 400# tongue weight. Could feel the stiffness with the minivan but not the truck.

The OP has stated that he will be carrying 1 quad (1st post), then 2 quads (another post). If only 1 quad located close to the camper (away from the tongue), then 800 lb. bars would probably suffice.

2 quads @ 700 lb. each placed on the platform (which appears to be centered between the axles and tongue) is going to put ~700 lbs on the axles and tongue. 1000 or 1200 lb. spring bars would be needed if that were the case.

The OP does not state what kind of WDH is going to be used. Equal-i-zer "spring" bars don't appear to be actual spring steel....the bend very little or none at all. Some members have even posted that Equal-i-zer tells them that using oversized bars is not a problem. There is little of no shock absorbed when using an Equal-i-zer......the trailer and TV suspension takes it all.

Other WDHs have true spring steel in the bars, where some of the road shock is 1st absorbed by the bars, then distributed to the trailer and TV. In the case of a WDH with true spring steel, sizing would be important to give you best ride.

When initially getting my trailer set up, I tried 1200 lb spring bars, and the ride was much too stiff. I went to 800 lb bars with my 700 lb. tongue weight, and the ride is much better.

You can see the bend in the bars:

The WDH I purchased is the Pro Series 49904 Weight Distribution Kit, it came with 1200# bars. I am still waiting to hear from Forest River to see what they have for data on how the hitch weight will vary with loading.

Please Post that Info on varying hitch weight with loading,when you receive it from F/R. Youroo!!

I finally received some good responses and the factory spec sheet from Forest River. This was their response;


So the tongue should always be around 7%-10% of the trailer weight, loaded unloaded, doesn’t matter. So say your at the GWVR of 5200, tongue weight shouldn't exceed 520lbs. But if you put a four wheeler on there and put it closer to the tongue rather than stowing it closer to the units wall, I will say I bet more weight will fall onto the tongue.


I am just going to have to wait until the camper arrives and I can do some experimenting. Thank you for all of your responses!

That 7 to 10% number surprises me as all the advise I have seen says 10 to 15% is normal.

I know, I have always heard 10 to 15% as well. One friend was adamant about 11% exactly was the ideal weight.

Just my experiences: I think the ideal tow weight depends a lot on the aerodynamics of the towed vehicle, and the suspension of the tow vehicle.


Towing boats, the recommended range is usually 5-10% of the tow weight. I always stayed to the 5% end, and had a good track record. But most boat trailers I have owned allowed movement of the axle(s) to get the tongue weight right. The one time I did get the tongue weight too light - 6,000 lbs of sailboat and trailer with 200 lbs of tongue weight - that was the scariest sway I had ever seen. Put it back to 350 lbs on the tongue, and all was good.


My Coleman Westlake PUP would go into sway at anything above 62 MPH behind my 1993 Ford Explorer. My current set up - 2800lb A-frame (as towed) towed by Hyundai minivan - porpoised during a test drive at the dealer's lot. Adding an Equalizer E2 took all the drivability issues away. I like the 11% target figure myself unless the camper is particularly aerodynamic, but am currently towing with more.

I don't want to hijack this thread but I kind of have a question in reverse order.

My question is this. I have an Equalizer WDH at 1200# bars. I am trying to avoid a purchase aof nother one but am wondering if ther will be a problem if used on a trailer with weight of 5200# and smaller tow vehicle. Will this be a problem?
