How Much Tongue Weight Am I Losing ?

[rideandslide]

Just recently started using the rear fold up cargo rack that came on our Grey Wolf 26RL. I removed the spare tire mount, it just hung to low to the ground when folded down for my comfort. I hall a cooler ( with a few beverages in it ) a water tight tote ( hold power cables, water hoses, etc. soooo much easier when we set up ) stuff that use to be in the slide storage area, and our portable waste tank (we call it the turd toter ) . All toll, i would say, maybe 100 #. I know weight all the way in the rear is going to take weight off the tongue, just wondering the ratio ???

Thanks Jim & Pat

Interesting question.


There should be some way to make a formula if you assume the normal 10% tongue weight. But, other than weigh it and know the length from the bumper to the axle, I do not know how to do it.


I would bet it is under 10 pounds.

Divide the distance from the axle to the center of your storage box by the distance from the axle to the hitch ball and the multiple that number by the total weight of your cargo. Your TT is just a big teeter-totter. For dual axle use a point half way between them as an approximate. However, the decrease in the tongue weight will be less than the resultant number because some of the load will be taken by the second axle. The amount of difference could be calculated but you would have to know all the parameters of your axle suspension.

Here's the only way to know for sure. Or a truck scale.

in many cases.. 50 to 70 percent of added weight..


if 100 pounds added at rear.. 50 to 70 pounds removed off of front.


in many cases.. not worth ....

Its taking weight off the tongue, but do you really know what your tongue weight was in the first place?

Advertised tongue weights are irrelevant - my trailer's empty tongue weight (with empty trailer, no battery, no propane tanks) was 200 lbs heavier than the manufacturer's claim.
