For every pound you put in the garage area - how much comes off the tongue weight - I know there is a definite science to figuring this out - but looking for a ballpark calculation!IE. every 10 pounds will take off 2 pounds from the tongue?We have a tow behind Rubicon 2900 toy hauler. I'm not sure where the water and waste tanks are, and we do travel with 1/2 tank of water (normally).I will have to have my DH climb under the trailer and see if he can locate the tanks - however I think the underbelly is enclosed.....

It is always a ratio of distance and weight.http://www.psychometric-success.com/aptitude-tests/mechanical-reasoning-tests-levers.htmhttp://www.engineeringtoolbox.com/levers-d_1304.htmlIf the distance from the center of the axles to the ball/kingpin is 12 feet and you place 100# 6 feet from the center of the axles toward the rear you will reduce the pin/tongue by 50#.

Lots of variables. Where are water tanks located at, where are grey/black tanks located, do you travel with full water, do you empty all of your tanks before you leave etc? How many axles, axle distance from the front and rear. etc.In my experience, my water tanks are in front of my axles. So when I have full water, my pin weight goes up even though I load a 2700lb sand rail in my trailer.

There really are to many variables to predict this with any level of accuracy. The only way is to load up your rig and go get it weighed. As each toy hauler varies depending on the placement of the axles, where the water/grey/black/fuel tanks are and of course what is being loaded and how far to the rear that weight really is. When we loaded our Raptor I notice only a couple hundred pounds came off the tongue weight with our two Sportsman 500s all the way to the rear.

Water tanks have nothing to do with the formula for calculating the change in placing weight in your garage. It is strictly relative to wheel to ball/kingpin (distance) and the distance behind the wheels you place the weight.If you are asking about how much your water tanks affect the tongue/pin you can calculate it based on where they are located and how much you put into them.To calculate your tanks affect - where are they (distance) and how much is half? It is just simple math.

Depends on your trailer set up but very little weight actually comes off the pin or tongue..... probably in most cases less than 100 lbs & as others have said it can add more......
