So as others have said your issue will be ride quality. That in turn will depend on how you load the trailer. The heavier your tongue weight is the less bouncy the stiff wdh will feel. Of course, you don't want more tongue weight than you need, but you do need your tongue weight to be at the very least 10% of total trailer weight to avoid sway. 

p.s. I was going to get a fastway e2 6000lb WDH, but the seller was nice enough to include it with the sale, so don't want it to go waste. plus already bought a sway control bar for it to be on the safe side. 

Safe travels!

For those with a full-size pickup truck with a 1,000 lb tongue rating, your pickup’s suspension is already so stiff that the WDH spring bar rating of 600lbs vs 10000 lbs wont hardly be felt. But the stiffness will be noticeable on a 500 lb rated vehicle like Renhui’s. 

Bear in mind that you have multiple weight specs to stay within. Tow vehicle front and rear axle load, max tow rating, tongue weight, vehicle gross weight, and max combined vehicle weight. Plus trailer gross weight and trailer axle weight. Tensioning the wdh increases trailer axle and tow vehicle front axle load while reducing tow vehicle rear axle load. Some think that the wdh reduces tongue load but it doesn't unless specifically allowed in your TV owners manual  

So setting all this up right is quite literally a balancing act. If you boondock and have a mid sized rpod will find it challenging to stay within all your ratings with a 5000 lb TV. The 500 lb tongue weight rating can be particularly difficult to manage. 

If all this sounds complicated it's because it is. With a heavy tow vehicle you don't need to spend much time on it besides knowing your real world trailer loading, but at a 5000 lb tow rating you and I don't have that luxury.

So when you go to the scales have both your trailer and tow vehicle fully loaded, fuel, supplies and  water in the tanks, people  gear, and pets, as you actually plan to travel. You'll be surprised how it all adds up. Bring your wdh bars but leave them off.  put them in the back of your TV. If you leave them tensioned it will mess up your weight readings.

This calculator will help keep track of everything  You can adjust your wdh tension in the calculator later to see what the effect is. The objective is to get the load on the TV front axle back where it was without the trailer. Not to level the TV as some folks think.

My 2016 rpod 178 has a dry weight of 2786lbs, and I don't plan to carry full water tanks etc. so try to stay below 3500lbs.  (one of the reasons getting an Rpod is the light weight, so I don't have to change my TV, but let's find out soon). 

I'll definitely hit the scale station when the weather warms up in a couple months.
