I'm adding a lightweight cargo carrier to the rear of my travel trailer by having a receiver welded on to the frame. So, the carrier will weigh 28 lbs. (unloaded) and I wouldn't carry more than 200 lbs. of cargo on it. Is there a mathematical formula that can be used to determine how this will reduce the tongue weight? My trailer, fully loaded for travel is 6500 lbs. Will adding 230 lbs. in back of the bumper reduce the tongue weight to cause a problem or require tweaking the WD hitch? Thanks for any help you can provide!!
It may. you could take a bunch of measurements, use some physics calculations to figure out how much it will reduce tongue weight. In about the same amount of time you could actually weigh the tongue before and after and not have to worry about goofed calculations.
Since the distance from the axle to tongue is usually longer than axle to bumper, it likely won't reduce tongue weight by 230lbs, but it could be 100-150lbs. In any event you want to make sure you don't go below around 12% tongue weight.
