Well go ahead and use a 1400lb hitch on a TT with a lightweight frame and 600lbs of tongue weight then see what happens when you go over a dip in the road or in/out a steep driveway entrance! let us know how that works out. the WD hitch bars are spring bars and need to flex to work properly. this is fact and not opinion! So yes they need to be sized to the trailer you have now and not one you may own 5 years down the road, besides you can replace the bars when you buy a new trailer!
Your above ridiculous scenario just proves the point I was trying to make that some posts like yours are sometimes not even worth what we paid for them .... Nowhere did anyone, Equal-i-zer nor those that spoke with the folks at Equal-zer even hint at what you are now suggesting to be O.K.
Larry, perhaps you missed the previous post by the OP in which he speculated:mfoster711 wrote:
In my opinion, the amount of weight being distributed from the trailer to the TV is determined by how the hitch is setup, not by the weight rating of the hitch. In other words, I could use a 14k hitch or 6k hitch on a popup and as long as both are properly setup then the amount of weight being distributed would be the same.
In this example, if we were using an Eaz-lift WD hitch, the number of washers used at the shank and the number of links used on the bars would probably be very different between the 14k hitch and 6k hitch when used with a pop-up. But, if setup properly, both should still work the same. Of course, it is very possible you might have difficulties setting up the 14k properly for a pop-up because the springs are too stiff.
IMO, the post by
dodge guy is an entirely appropriate response to the OP's belief that it would be okay to use either a 6k hitch or a 14k hitch on a pop-up.
The OP has made reasonable comments, and they deserve more than a "ridiculous scenario" response.
A dip in the road or steep driveway entrance, where the TT's rear tires are are below TT's front tires and the TT's tires, will cause the WDH to exert more force on the A-frame.
That's not an opinion -- it's a simple result of physics. The stiffer the WD bars -- the greater the added force.
Similarly, when the rig goes over a hump in the road, such as a RR crossing, the load on the WD bars will be reduced. The stiffer the bars -- the greater the unloading. This temporarily can reduce, or completely eliminate, the load transfer to the TV's front axle.
It is theoretically correct that both a 6k hitch and a 14k hitch could be set up to give the same amount of
static load transfer. This can be verified on a scale.
However, in a dynamic situation where the vertical angle between TV and TT is changing, the stiffer bars will cause greater changes in bar loading and load transfer. This can adversely affect both ride and handling.
Also, as pointed out by the OP, with the stiffer WD bars, it can (probably will) be more difficult to fine tune the load transfer. With a stiffer bar, adding/subtracting one washer or one chain link will have a coarser effect than with a more flexible bar.
The OP also is correct that the amount of load being distributed is determined by how the user chooses to set up the hitch -- not by the rating of the hitch.
If you want to restore only 50% of the load removed from the front axle, you certainly won't be using 100% of the WD bars' capacity.
Even if you restore 100%, you probably still will not be using 100% of bar capacity.
If you subscribe to the antiquated approach of adding equal loads to TV's front and rear axles (and actually can achieve it), you might get close to 100% of rated bar capacity.
Equal-I-zer sells WD bars with ratings of 400, 600, 1000, 1200, and 1400#.
You should be able to purchase a hitch with bars which are closely matched to your particular needs based on how much load transfer you desire.
Or, you can purchase based on the expected loaded tongue weight.
Or, you can purchase based on any degree of conservatism you desire.
It's your money and your choice.
Then you can report your experience and become another entry in the anecdotal data base.
