Weighed my rig on a single agricultural scale over the weekend.
07 Ford Expedition and 04 Rockwood 2501 (no slide)
Truck Specs: GVWR 7400, Max GCWR 15000, Max Cargo 1584
TT specs: 25' 1". Dry hitch 258. Axle wt 2995. Dry wt 3234. GVWR 4658.

Truck wt 5860
Front axle 2860
Rear axle. 3000

TT wt 5160
Tongue wt 500
Front axle 2820
Rear axle 2460

Combined truck & TT. 11,040
Truck only while connected 6280
Camper only while connected 4820

So am i transfering the axle weight sum difference of 120# to the truck? And why is there a 60# difference between each vehicles connected weight when added together???
I was amazed that my tongue wt was so low. No wonder I have sway issues.
Also was surprised that I was over the TT's GVWR. The question is what can I do? If I add weight ( maybe water in the fresh water tank thats under the front bed ) I'll just be adding more wt overall.
Anybody else in this predicament?

Was your trailer loaded up to camp? Food, clothing, etc..? It it was id consider putting some stuff in the TV and shifting some other stuff into the front of the TT to add to your tongue weight and help with the sway.

Mostly Yes...Just missing the cooler which normally goes in the truck. Most of the stuff we first put in the back now goes beside the front bed (chairs, fold up table, etc). We did that early on to help the sway issue.

Do you really have 1900# of "stuff" in the trailer.
I'd be weeding out the stuff you never use to try to get the TT down to its GVWR for a start.
Then try to shift some what's left forward to get at least 12% on the hitch.
You mention WDH, do you have an anti-sway system?

My practice has found that my trailer tows so much better with the 50 gallon tank under the front queen bed full of water.
At the end of my campout I attempt to drain my 45 black and 45 gray asap. It makes a big difference to lighten up the waste water which is in the rear.
I put the heaviest stuff in my pickup bed.
The walkaround queen has the hydraulic struts Komfort 21T , and whatever is going into the trailer goes under the bed.
Twelve percent tongue weight works really good.

Did you get weights of the tv axles both with and without TT hooked up? We rearranged things in the TT so heavy stuff under bed and in pass thru. We have only a few very light things in the pack n play in the back.

thanks for all the input. as stated there isn't much cargo capacity on this Rockwood. So there is only the EZUp that we feel we can leave home. That is heavy and should help.

The numbers are correct unless I screwed up what i measured. there is no weigh slip or ticket. we weighed each time and walked over to the building to see the scale display and wrote it down (this is a farm operation that leaves the scale on for the community).
Oh, and this Rockwood only has a 31 gallon fresh tank plus the 5 gallon HW tank.

He is 502 pounds overweight on the trailer (based on the figure of 5160 stated for the trailer -- more on that number) but 1540 under the GVWR of the truck. The combined weight is not an issue. He needs to figure out how to shift about 800 pounds to the truck, then fill that water tank. Or figure out how to shift more weight from the back of the trailer to the front (even then, about 800 pounds being shifted into the truck needs to be done).

The trailer only had about 1200 pounds of carrying capacity to begin with. If it has a 38 gallon water tank and a 6 gallon hot water heater (plus about 2 gallons in plumbing), that is about 385 pounds right there.

Now there are some problems with these numbers. The front and rear axles of the truck add up to what is stated for the the total of the truck. But the weights of the trailer don't add up. The sum of the front and rear axles of the trailer is 5280, which exceeds the stated weight of the trailer (5160) by 120 pounds. Then when you add in the stated 500 pounds of tongue weight, you get 5780 pounds for the trailer. This would be 1122 over the GVWR of the trailer. So the OP needs to go over the numbers better. It is sometimes difficult to keep all of the numbers from a scale ticket straight to understand what they mean.

The front axle being more than the rear axle on the trailer would be an indication of it being a little nose down. If it is actually light on the tongue, this means the hitch is really not set up right. Fixing the hitch might also help with the sway problem.

If the true weight of the trailer is near 5800 pounds, 750 pounds of tongue weight would be better. That is only 250 pounds. For every pound moved from the rear to the front, you will get an increase in tongue weight of 1.5 to 2 pounds. So it would be a matter of finding about 90 to 100 pounds of stuff that can be moved. That is also about the weight of 12 gallons of water. Are there some cases of soda or beer in the back? How about a cooler stashed back there?

He has already got 360lbs more on front axle than rear or did you rewerse them?
