5th wheel weight question

FWIW, I have a 26' 5er with rear kitchen and aft FW tank. I've done the math and 500# of water lowers the pin weight 100# and adds 600# to the axle weight. Your result may vary somewhat depending on length of trailer, size of tank and location of tank.

I usually travel with the tank full, because we mostly dry camp. Handles just fine.

Yes! Our 27', '94 Chateau had rear water tank under the futon and I found travelling with it full took a lot of weight off the pin.
Habit was to travel with only a couple of inches of water in it for on the road travel. We don't boondock.

I just have a question and it may be silly but I was wondering if you have a 5th wheel and the fresh water tank is at the very back. If you fill it (42 gallons about 500 pds) does it take all that weight off of the pin?

Thanks...

Well if this attempt to get the pin weight down to tow with your F150, keep in mind a lot of weight aft of the wheels, and a lighter than normal pin is a recipe a poor handling rig with a fare amount of chucking.

If it is aft of axles yes it will make the pin lighter. Basic CG the axles are the fulcrum. How much? That would require weighing it or a lot of math.

Best bet: Fill the water tank, and weigh the rig properly to get the hitch weight. Without knowing the exact rig you're talking about, my guess is a full tank of water would result in a slightly lighter hitch weight.

No. To figure out exactly you would have to take a lot of measurements and then do the math
