Tongue weight 25' FC FBQ

I just tried to calculate my FC's tongue weight using the bathroom scale method- one end of board 1 ft. from the hitch post, the scale located 4' from same point, lower trailer until full weight on board, read scale and multiply by 5. In my case, the scale read 240# meaning my tongue weight is 1200# which seems excessive. What I carry in front storage is hitch assembly, weight distribution bars, hoses, and plastic blocks, then under the bed I have a few items such as camp chairs, small grill, etc. I tow with a Ford F150 crew cab, short bed, maximum tow capacity of 11,000# and in my travels to date I have never experienced any towing issues.

So, it my estimate technique correct and reasonably accurate? If so, is this tongue weight in a normal or expected range for this trailer? Maybe I'd be better off not knowing, but in these times of social isolation I have too much time on my hands.

Hope everyone is healthy and practicing good social isolation.

Gary

My 25' trailer is a much older RB narrow body. My tongue weight is about 900 lbs. I did that with the bathroom scale years ago. The trailer adds 800 lbs to the truck when hitched and about 100 lbs is transferred back to the trailer axles. I would think your measurement is close. Static tongue weight does depend upon the trailer being level or at the same angle as when hitched. I am one that thinks tongue weight is pretty much a plus for towing stability. In your case a hitched weight on the front and rear TV axles and a unhitched weight on those axles would be instructive. Just one pass through with the trailer hitched would be very instructive. If you can do that now? Even if the TW is 1250 I do not think I would try to change it.

Probably a pretty close weight. Our 2014 FC 25 FBT, with a ProPride hitch has a tongue weight of 1,200 pounds. I weighed it using one of the trailer specific scales. The 25 footers seem to have more tongue weight compared to bigger Airstreams.

The last one I weighed was 990#, with full LP and water, and no hitch parts installed.

1200 lbs tongue weight is too much for a 6000 lb trailer. That's 20%. The normal recommendation is that the tongue weight should be between 10% and 15%. If the tongue weight is too high the rig will be more prone to jackknife in a hard emergency turn. If it is too low the trailer will be more susceptible to sway. I would look to redistributing the trailer contents, putting heavy items more to the center of the trailer.

Is your scale actually under the hitch, or are you using the jack? Weights will be different ...

2014 25 ft front twins. When new, not loaded, no hitch ,one bottle propane with whatever the dealer put in, weighed in about1040. Since then have installed, pro pride hitch , filled both bottles with propane, ( many times) enlarged battery box to accommodate bigger batteries (2) , filled both front side (2)and front compartments with all of neat stuff one needs, bedroom cabinets have clothes, necessary sheets and whatnot , and I consistently weigh in give or take...1175 to 1225. From what I have read that seems to be pretty average. Oh yes ,done with a shurline scale. I keep that under kitchen seat . ( in the back).
Done all 49 states ,( no Hawaii) all the provinces except Labrador and PEI. Never had a problem. Enjoy it!

Under the hitch and level trailer, to get the proper tongue weight.

last year at a rally, we had a meeting of the minds where we measured several trailers for tongue weight. Four members brought their Sureline scales, so we tried each scale on different trailers.
My 2010, 25 fb converted Q to twin weighed from 950 to 1100 pounds. That was the low and high weights.
Which scale do I believe, 4 scales, 4 different weights?

we leveled the trailer each time.
we averaged the weights and mine was 1025#
we used same procedure on different size trailers from 19 to 34 ft with about same results. ALL above what AS lists for tongue weight.
None were compared to Truck scales.

They are not certified scales...the dial on our 2000 is in 50lb increments.

The positive side you have a lot more info than most.👍

POI..you get the most accurate from directly under the ball.
CAT figured TW is actually not tongue wt, the weight is taken at the TV rear axle.

The Sherline scale gives erratic readings if there is an air bubble in the oil.

This was al done as part of our Tech Talk" at one of our rallys.

There was alot of room for error, but was interesting in seeing the different weights measured.
There was room for error in how the 2x12 used as a base for the scale sank in the ground, what if the measurements were done on a more solid surface.
We realized these measurements would not be correct, but it was a start.

We had a 2015 FC FB 25. We had it weighed at the scales and hit 1300 lbs. we weighed several times and called colonial. Not surprising to them. With tanks full, water and wheel base this is a true weight. There is an extensive thread on this topic if you research it in the forum web site. You can only get the weight down if you do not use the external lockers. Do not go by the brochure!

There will be variations in TW due to hysteresis (look it up) on dual axle trailers due to how the tongue was raised and/or lowered prior to measuring. Don’t sweat it.

Our 2018 25ft FCFB torque weight is 1125lbs. Odd a CAT scale.
