Is that a bit light for 2600 lb tow weight?
Yes, 200 pounds is less than 10% of the 2620 pound total.
However, I believe that the light tongue weight is mitigated by the double axle, and my use of a Weight Distributing Hitch. This is the most stable trailer (never any sway) that I have ever experienced.

Thanks for running an interesting survey, Frederick. Isn't it surprising that while most trailer owners underestimate the weight of their trailers, as a group we overestimated the weight of this Fiber Stream, even given an actual empty weight to start from? Overcompensating, perhaps?

I hadn't voted yet, and was going to just assume that same cargo load as me (about 600 lbs) and thus guess 2600 to 2700 lbs. Honestly!

Can we assume that the 2620 lbs includes the 200 lb on the hitch (that it is not just the axle weight) and that this is determined without effects from the WDH?

I am not so concerned by the tongue weight of less than 10%, but the combination of a very light hitch load with a WDH does seem a little strange. I assume that the spring bars are set to a very light load, and this setup is serving mostly to spring-load the coupling to centre, resisting yaw and roll, while adding some frictional damping as well. I think it would be interesting to know how well the rig would work without the WDH (and its weight). I see in the inventory list that there is also a friction-type sway control.

Although I'm not convinced that tandem axles are worth the weight and bulk, they seem to be working for Fiber Stream owners, who seem univerally happy with their trailers. Further evidence that building a good product has little to do with commercial success.

I've never seen specs (overall length, body length, body width, interior height, outside height, axle capacity...) for the Fiber Stream, but I understand that it is a "16 foot" design. The 2000 lb empty weight does seem to be typical for that size of moulded fiberglass trailer.

As for the final number... I wish my trailer were only 2620 lb, but the accommodations in any of the 16' designs don't seem to quite fit what we are looking for. It would be a better match for our "3500 lb capacity" vans than my current setup.

(1) To weigh the trailer, I completely unhitched it, totally on the scale platform, with my tow vehicle off the platform, and the readout was [b]2620 pounds. Then I hitched up, but did not install the WDH spring arms. With the tow vehicle off the scale and the trailer on the scale, the readout was [b]2420 pounds. I deduced from that a hitch weight of [b]200 pounds.

(2) The WDH components (excepting the ball mount) and the friction anti-sway control were included in the items that the previous owner transferred to me when I bought this trailer. I use the WDH because of Honda's owner's manual stating that it is required when towing any trailer over 2000 pounds. I seldom use the friction anti-sway... unless I am towing in very windy conditions.

(3) I can post the complete specs here later...

  1. Nicely done. I haven't done it this way, because I didn't want to be on the scale and immoble when an truck came up to use it, but it is certainly the most accurate method.
    The spring arms will add their weight to the hitch weight. When tightened, they force load off of the rear axle (on to the van front and trailer axles), but their weight is still there. They probably put the tongue weight up to 10% of the 2620 lb by themselves.
  2. I didn't realize that Honda wants the WDH when over 2000 lb, regardless of hitch load. Toyota previously specified "sway control" over 2000 lb for my Sienna, but later dropped even that. WDH is only needed as required if the hitch load is over 350 lb. Of course, following the manufacturer's requirements is prudent.
  3. I look forward to the specs, but of course there's no rush.

Hay u got me thinking.every year our load gets bigger time for over loads.at one time we had 780 lbs of stuff between the truck and trailmite. Than i got a dutch oven & fire wood. i ve lost count O and the dogs stuff. & Two people. & the list grows. thanks LEE

Yes, Benita, That makes sense to me.
I believe I remember the differences between out units. You have a little more weight to your interior. Mine is just the fiberglass shell, painted on the inside much like the very first Bolers. No Ensolite, No Reflectix, No Rat Fur, and My panneling is only on the interior partition walls. You also have a roof mounted air conditioner and a separate furnace that I do not have. And I seem to remember that you have more than one spare tire...

Good topic Fred!
But given your parameters, I can't play either. We gotta lead egg! Loaded and ready to roll for an extended trip ours weighs right at 2T, w/ 600# tongue wt. Extensive frame and tongue alterations, 15" wheels/tires, 3000 watt generator an extra battery and 2 full propane tanks on the tongue all contribute. The WDH is required but the sway control doesn't seem to do anything. For our needs, our one-of-a-kind 17' FD Casita functions like a dream. 17' was before 2 ' extension for the generator and the A/C unit on top also contributes to the weight.
Perhaps starting this discussion will contribute to an awareness of a little of the physics involved in towing and more importantly stopping our TT's.
Enjoy all the aspects (including planning and execution of mods) of owning one of our FG jewels,
Kurt & Ann K.

Great info, Frederick!

Just one little question... is that 3500 lb per axle, or total for both of them? It sounds like way too much for each axle (especially with 12" tires), but 1750 lb seems like a strange single-axle capacity. Maybe each axle is higher (e.g. 2000 lb), but the trailer is rated for a total of 3500 lb between them...

I know the fiberglass shell is thin, but if the King bed runs long (80") direction across the trailer (and 75" along the seats in the fore-aft direction), and the outside of the body is 80" wide, there nothing left for the 'glass! I'm guessing that all dimensions are approximate, the body does taper a bit bottom-to-top (so maybe the 80" is at the top?) and the shell without lining is probably only 1/8" anyway.

Actually, 3500 Lb is "stopping capacity" of the brakes on the leading axle, (trailing axle is brakeless) according to the doccumentation. There is no doccumentation of the axles' capacity. There is nothing legible on my axles, themselves. Each spring assembly has 4 leaves.

80" is the measurement at the widest point, near the bottom. Near the top it is 78" because the "Child's Upper Bunk" measures 27" x 78", with a 2" thick mattress. (all other cushions are 4" thick) The taper is so slight as to be just discernable. I can verify, after removing the windows, installing new putty tape, and re-installing them, that the shell is 1/8" thick.

Now I'm really curious. Frederick, do you know how wide and long (and perhaps how thick) the leaves are? The trailer axle world is full standards, or at least very common practices, so given the dimensions the capacity can probably be guessed. I'm wondering how much extra capacity was built in compared to a single-axle design, to account for the uneven sharing of load.

I had forgotten about the one-axle braking setup. The brake size is also indicative of axle series and thus potential capacity. With the 12" wheel size, I would guess 7" brakes, but that doesn't sound big enough for 3500 lb of "stopping capacity" (which would normally suggest 10" diameter by 2.25" wide drums).
