I am also shocked the dealer let you leave without a WDH. Our trailer came with one. Any amount of wind, or a sudden stop and your trailer will start swaying all over the place, putting not only your family but every other person around you on the road at risk.

Please get a WDH (frankly I would go back to the dealership and demand one!) and set everything up properly. I also agree the trailer is not sitting level and needs to come down a couple of inches. You'll be amazed at how much the stability will improve with both.

I can't find any more examples right now. When I bought my trailer tires it mentioned in the brochure that speed greater than 65 mph results in in lowered weight capacity. It didn't state NOT to exceed 65.

I knew you could add extra PSI to increase mph but you lose the load rating. Not sure what tires the OP has. If they're 205/15 then he's at the max load rating and if driving faster has reduced his load rating. If he has 225/15 then he's okay. But I'm not giving him the benefit of doubt that he filled his tires 10lbs over the max psi to be able to drive 75mph. Reason is that judging by his setup he hasn't got a full grasp on what it takes to be safe. So I doubt he's of the understanding in all parameters of towing.

Thanks for the links though. I learned something new today.

The trailer is setting straight, In that picture something in the road is creating that look. The truck itself has some sort of trailer sway control. Not sure completely how it works, It does have sway bars front and back, I actually think I saw two in the back. I wasnt aware its so dang mandatory every trailer has a wdh setup? Truck handles like a dream with it now. Now my previous truck didnt handle it very well that for sure.

That being said, it isn't the best idea to constantly drive faster than 65 when towing for a myriad of reasons. That is to each driver to find a comfortable compromise between speed and safety.[/QUOTE

It was for a short time, Just checking out the truck. Ill prob stay 60-65 most of the time. I also keep good distance in front of me.

Yes I am quite new. Glad to see we have such a smug expert with us.

Guys, this tt had a dry hitch weight of 635 and a dry weight of 5460. Add the propane tanks and some cargo (not much) now the hitch weight might be 750 and maybe a total of 6000. It dont seem like to big a deal. The trucks good to 8200 and I know of some others on the dodge forum that have hauled a good bite more than that with it even and the truck handles it fine. It says alot that it can run 60 mph at 1500 rpms (8th gear) including mild inclines without jumping down a gear to do it.

Between this truck and my previous one I have logged around 3k miles hauling this trailer without a wdh and have yet to feel any kind of wobble. If I get into a rough side wind I might just pull over for a time. I know I looked at one and it alone was around 150 lbs by itself. Maybe I am missing something but it dosent feel like it towing. Also wouldnt a wdh make it weird to turn sharp and backup ect?

The main function of a WDH is to "maintain" the proper weight on the front suspension of the TV while towing. As TT tongue weight is added to the TV's hitch ball, weight is added to the TV's rear axle and at the same time weight is removed from the TV's front axle. The heavier the tongue weight, the more weight is removed from the TV's front suspension......, and proper/safe TV handling of any TT is dependent on the integrity of the TV's front suspension.

In cases where a WDH is required but not installed, the weight on a TV's front axle can fluctuate while in tow, not a good condition in itself and is amplified if to much weight was removed in it's static condition.

One's TV owners manual will identify the condition that the front suspension should be when towing...., in most cases it is recommended that the TV's front suspension should maintain the same weight hitched as unhitched for ideal handling.

Visting a CAT scale under TV/TT loaded conditions will eliminate all the guess work, and tell you everything you need to know; if a WDH is required, is a WDH properly sized/adjusted, all TV/TT weights, proper loaded tongue weight (13% to 15%), etc..

OP, I am sure that Ram specifically states that a WDH is REQUIRED if you are towing over a certain weight or a certain tongue weight. Regardless of whether or not it is required, if is certainly a very good idea.


150 lbs seems awful heavy for a WDH. I have the Equal-I-Zer WDH and it can't weigh more than 75 lbs or so. It distributes weight to the front axle to help with steering and reduces (eliminates) sway. In windy conditions, getting passed or passing a large truck... my trailer is rock solid.


Especially if you are towing at higher speeds, you need to take every reasonable precaution when towing. Spend $400 and set your rig up right.

I can't imagine towing that trailer on a ram 1500 (remember I had a 2013 ram) without a wdh. Your tongue weight is likely 900lbs give or take. Rams rear coil springs r very soft. When i would haul 3 atv's (a little 90 in the bed) and 2 full size ones on a trailer, my rear end sagged a good bit and I could feel the steering being very light.

I think the Eco diesel is a great idea and you r likely right at your payload capacity with the family in the truck with the trailer, so I also highly recommend you check out an equalizer or comparable wdh hitch.
