Tongue Weight Conundrum

Ok, I took the rig down to the CAT scale ready to camp and came out with a tongue weight of 1060 lbs.

Trailer is a 2007 JayFlight 23FB trailer weighed in at 5500 on the dot.

Truck is a 2002 F150 which came in at 5180.

Current hitch is rated to 750/7500 with WDH. I am within GAWR for both axles on the truck as well as payload rating.

I'm a bit over GCWR but that I can correct. Trailer is my mind by no means overloaded I feel we travel pretty light compared to most. We don't carry freshwater with us so that isn't part of the equation.

Trailer has 2 30# LP tanks and 2 group 23 batteries on the tongue. Hitch is a 1k/10k equalizer 4 point. For fore cargo most everything is fairly light (small BBQ, light weigh chairs and table, awning lights, couple of totes iwth fairly light stuff etc ). I can't for the life of me figure out how tongue is coming out to 1060#. All the cargo we carry in the front of the trailer fits in the pass through, under the bed is completely empty.

I know moving cargo more aft will help with tongue weight, would moving most of it under the bed out of the passthrough area make any noticeable difference or do I need to look at moving further? I'm thinking I may go down to a single battery and possibly a single LP tank. We sip the LP and never boondock so having 2 batteries isn't much of a concern to me. Just looking for ideas on how to get this number down. Obviously I wanna get below 750, not sure if that's gonna even be possible or I just need to suck it up and upgrade the receiver to a 1k/10k with WDH receiver. WDH is out of whack to but I'll be able to get that inline once I get TW figured out.

Sorry for the long post.

1. Post your numbers so we can double check. I missed calculated TW initially and once calculated correctly I wasn't as bad as I thought.

2. I think you're going to have to remove 1 propane tank and 1 battery to even make much of an impact.

What is the payload from the door sticker of your F150? That listed TW is using up a bunch of it. I agree with Doug - I would remove 1 battery and 1 tank for starters...

It doesn't surprise me given your set up. I have 2 6V batteries and twin 30lb LP tanks on my tongue, and the same pass-through storage compartment as well. My trailer weighs in at 6800lbs ready to camp and the tongue weight was 920lbs. Your trailer is a lot shorter than mine and has less weight behind the axles than mine does. My extra weight behind the axles counterbalances the tongue weight resulting in slightly less than what you are coming in at. When I add the bikes and bike rack at the rear, it drops below 900lbs.

If I were you, I would get a hitch put on the rear of your trailer and get a cargo rack or box back there to store some of your stuff. It will relieve tongue weight by removing it from the front pass-thru and adding it behind the wheels. You should be sitting around 800lbs of tongue weight with that trailer.

I hear ya, the tongue weight numbers on these trailers is even further off than the unloaded weight. I am guessing that the tongue weight must be calculated with the trailer totally empty, with tanks removed, with batteries removed, with tongue jack and coupler removed, with spare tire (if forward of the axles) removed, with bed removed (if front bed).
I got the rear hitch from Jayco. It is a massive piece of metal, but even with that I am going to reinforce it a bit more. The brackets do not appear to be welded onto the trailer all that securely, so I am going to have them redone. Also the hitch is bolted on with 4, 1/2 inch bolts, too small IMO. So I am going to drill that out an put in some larger grade 8s. Have to be careful loading onto the back of the trailer. Anything back there can take a real beating.

Ok, so my three weigh in's were as follows.

1st - Truck Only - SA 2810, DA 2360 total 5180
2nd - TV w/TT WDH Engaged - SA 2600, DA 3260, TA 4820, total 10680
3rd - TV w/TT no WDH - SA 2500, DA 3420, TA 4760, total 10680

GAWR for truck is 2800 SA 3800 DA, GVWR 6050, payload 1945.

I know the WDH is out of whack, but I'll have to correct it once I get TW figured out.

Seems pretty high a TW of 1060 lbs. of a TT with 5500 lbs. Do you have gold bars hidden in the A-Frame? Do you use a TW scale?
My TW is 850 lbs. on a TT weight of 5900 lbs. and I have 2-30lbs propane and 2 group 27 and 30 gallon FW. Storage compartment is loaded with tools etc.
Proper distribution of cargo is very important.
In North America the recommended TW is 10 to 15% for TT, in Europe they recommend 6 to 8%, Australia takes after the European model.
Sway increases with speed and the cause is improper weight distribution.

Based on your weights I get a Loaded Tongue Weight of: (2,500lbs + 3,450lbs) - (5,180lbs) = 740lbs

Hey, I did the same thing back in 2012. I thought maybe you might have made the same mistake.
