How much weight does a WDH reduce tongue weight??

[EricRom]

If I have a 1000lb tongue weight, using a Reese dual cam WDH what can I expect the tongue weight to be. Thanks

[wmoses]

Hitch capacity is reduced by the weight of the WDH that is mounted there.

[DieselX]

It doesn't reduce the tongue weight at all, it transfers some of the weight to the steer axle.

[EricRom]

My hitch sticker says 1150lbs with WDH, is that too close. I will still have 700-800lbs left of cargo capacity.

Assuming the 1,000lbs is the "loaded" TT tongue, a properly sized/adjusted WDH will distribute weight off the TV's rear axle to the TV's front suspension and TT axles. The objective is to return the same weight removed from the TV's front suspension back to the TV's front suspension from when the TT's tongue was initially placed on the TV's hitch ball.

As mentioned the weight of the TT's tongue that is placed on the TV's hitch ball for the most part doesn't change..., but the WDH when engaged may remove a "little" weight off the hitch ball, if any.

If by "hitch sticker" you are referring to the TV's rear mounted reciever.., I would like to ask the following:

* Is the 1,000lb tongue weight from your first post "unloaded" or "loaded" weight?
* Is the 700-800lbs cargo capacity "remaining" after subtracting the TT tongue weight?

We looking to order a Jayco Eagle 314BDS with a dry hitch weight of 930 and my TV is a 2012 ford f150 crew ecoboost with max tow with a payload of 1740lbs which includes 150 for drive and full tank of fuel.

EricRom,

I thought the F-150 Ecoboost with the max-tow had a little higher "payload capacity" (2,550lbs ??), but I will assume it is 1,740lbs per your post. Also, the TT's 930lb tongue weight is a "dry" (unloaded) specification.

The Eagle 314BDS has a UVW of 7,465lbs, add 350lbs for actual ship weight, add 125lbs for battery and WDH, and another 800lbs for "stuff" (not including fluids in the tanks). The "conservative" sum total would be a loaded TT weight of 8,740lbs (GVWR of 9,975lbs). The desired loaded tongue range would be 13% to 15% of the TT's loaded weight.., thus a loaded tongue weight of 1,136lbs to 1,311lbs. This also implies that a WDH rated at 1,500lbs would be desirable, and that the loaded tongue weight is subtracted from the TT's payload capacity (less passenger and cargo weight as well).

If in fact your TV's OEM receiver is rated at 1,150lbs in WDH mode, then the receiver needs to be upgraded..., assuming that no other TV weight limits are exceeded.

Rustic Eagle, the 2,200 pounds you reference is with the Heavy Duty Payload Package.

EricRom, you will undoubtedly be overweight. When you are loaded, you could exceed the rear axle rating as well if you have passengers and a bed with cargo. Trust me, Ive been there twice. A trailer with a togue dry ar 930 will be more like 1150 loaded with front storage.

[EricRom]

Ok if I have a 1150 tongue weight payload includes 150 for driver and a full tank of gas so add 100 for me total 130 wife 80 for son and 50 for daughter which will total 1510lbs in cargo which will leave me @290lbs left for gear in truck which should be good and other gear can be loaded in rear of camper.

I don't know if this will help you but it did for me after I struggled with all the same questions on weights. I stumbled upon this after I got great information from Bob (Rustic Eagle) and others on this forum when I initially asked questions about Weights, Weight Distribution, and TV (I just could not calculate it myself). Follow these links plug in your numbers and it will really give you a starting point.

IMHO I think the trailer is too much for an F150, I struggled with since I have a 2011 F150 max tow package, etc. about the same setup. We initially wanted a Jay Flight 29RLDS then a Jay Flight 26RLS and realized that even with safety margins, a loaded TT and TV I would be substantially over weight (Validated with this at the CAT Scales). Since I am not willing to get a new TV I fit the TT to my vehicle so we are going to be getting a White Hawk 30DSRE with a ProPride Hitch. I just could not risk putting my family in danger....I have a member of my family that had a slightly overloaded setup and they flip the whole thing, TV and TT, on Interstate 77 in Virginia. They were lucky and came out with just some cuts and bruises, the TT and TV were a total loss.

Note this is only my personal opinion.

I would agree with Gary's (glcamp) conclusion: the trailer is too much for a F150. Using a F150 is putting the F150 at risk, the occupants therein, and those of us who travel on the roadways. Bottom-line: either get a different trailer (eg, pop-up) or a different TV.

Thanks for the clarification...., I knew that there was a F-150 Ecoboost "package" that put the payload capacity over 2,000lbs.

Pop-up, are you kidding me I guess you are one of those speople if you don't have a one ton dually you can tow anything. I currently town a 34ft keystone passport 300bh at around 6400lbs with not a problem. This truck tows way better than my 08 Chevy 2500hd with the 6 liter but maybe not as good as my 06 duramax. You guys should check the YouTube video off the ecoboost towing two race cars at a total of 11300lbs around a race track at an average speed of 85mph for 24hrs straight.

It's not helpful to the OP to discuss max loads, race tracks and running 20 mph over an ST tires rated speed.

When you guys use the word transfer of weight then to me that means that weight is being moved off the tongue and distributed to front of TV and axles of TT, so how is it not reduced. We do not load very heavy, short trip (2-4) days we pack the food and coolers and longer trips we wait and buy food and drinks when we get there. 99% of the time we camp is with full hook up so we never fill the fresh water tank. I have call dealers service people and sales and half will tell me I am fine where as the half say it maybe to heavy as same goes for all the forums. I just want to get the closest TT to what we want and not get a new TV, of not I will keep what I have and wait till I can get a diesel.

It is leverage. The weight of the tongue does not change. It is not easily explained. Weight is transferred from the rear axle to the front axle of the TV and to the trailer axle. If you could measure what the leverage is doing at the ball you would find that the force on the ball itself actually increases. As I said, it is not easily explained. But it is all leverage.

Who is watching the watchers? Lol

Good to know we can respect everyone's opinion here and we all care about safety!

EricRom,

Another way to look at it is that once the weight of the TT tongue has been place on the TV's hitch ball it has an immediate effect to the TV's front and rear axle loads (weight)...., the TV's front axle has weight removed (front of TV rises) and the TV's rear axle gains weight (rear of TV squats). As the WDH is engaged the force generated by this leveraging action is transferred through the WDH ball mount, the TV receiver, TV frame, TT frame.., all resulting in weight changes over the TV/TT axles. Do to the dynamics taking place at the ball mount, there is very little (if any) weight actually "removed" off the hitch ball.

Some folks may compare the weights being distributed to their loaded TT tongue weight value, but the major source of the weight being distributed is coming from the weight placed over the TV's rear axle.

For a detailed/technical overview of how a WDH works, the following link may be an interesting read: http://www.rv.net/forum/index.cfm/fu...d/14265335.cfm

It should be noted that since some weight is distributed to the TT's axles, thus reducing some of the weight being carried by the TV. This WDH process is best appreciated when one takes their TV/TT combination to a CAT scale, eliminating all the guess work.

Hope this helps.

Bob
