Steve Caseys. I too think they put on the wrong springs. It was the axle mfr that said trailer has been overloaded and if so, then its built wrong because I've never used it. BUT, while I'm getting it fixed I'm thinking 7k axles would be just the ticket and give me some extra strength for when off road a little bit. I would not consider the capacity to be increased by 2k.
As far as pin weight, that was just an example. Actual pin weight with unloaded trailer is 1820.
1820 + 9860 (both trailer axles) = 11680 empty (actually full of propane and gas + 2 12 volt batteries). Max capacity per sticker is 13,540.
Weight on front trailer axle is 4480, on rear is 5380. This was determined by pulling front axle off CAT scale and weighing rear alone and subtracting from 9860.
It sits nose high when on my truck (yes...I can lower my hitch to remedy that) but nose high is ultimately what got me looking at springs. I wanted more lift so I can maintain the gap at bed rails and when the spring shop looked at it they said they're nearly maxed!
I took pics with my phone but they don't show much. You really need to eyeball it to see how the left rear spring is just slightly going up in the center. There is still some bow left on the outer ends but 2 guys have said it shouldn't be like that at the center.

You definitely need more capacity. Both the 300x10 and 300x12 are severely lacking CCC. Especially if you have a fuel station behind the axles as well.
4 bikes, fuel and water will easily push you axle weights over the limits. Not to mention you pin weight may end up way light loaded.
My axle weights went up nearly 4K with 2 atv's, 1 bike, fuel, water/food, and clothes.
Every time I look at the specs for those models, I wonder what they were thinking only installing 6K axles.

Still too light on the pin for a trailer with a bedroom slide.
Unless you carry 150 gallons of water and your tanks are completely at the back of the trailer.

I don't know what you mean...it is what it is...I can't change it unless lowering the hitch will shift weight forward...which I think it will some, but not a bunch like you seem to be expecting. It is currently 15% of the trailer weight which seems to be in the ballpark.
The trailer holds 100 gallons of water and the tank is over the axles. The black and shower holding tanks are forward of the axles and the kitchen one above the axles or just in front of them. The hot water heater is forward too. All water tanks are empty...and there is nothing in the trailer other than what I listed....well...a little etrack in the garage.
The bedroom slide is a wardrobe...it isn't big...additionally, there is alot of forward storage in the trailer under the bed (it lifts up) and in the cargo bay under the bedroom.

So...some good news! Forest River is shipping out new springs and axle tubes to the dealer. They won't send 7k axles as they maintain that they aren't needed. If they send me .25" wall axles, I have a company who will buy them from me and I'll be able to buy 7k axles from them.
As previously mentioned, if I can get this done I won't view trailer capacity to be like 16k and won't load it as such. For one thing, my truck can't handle that much. Plus, the tires are a possible limiting factor...and frame design probably too but I have no way of knowing that...plus I'll still have 6 lug wheels.

Good to hear. The springs should make the difference if they get it right this time. I'm pretty sure you are getting Dexter axles and probably the 6000lb regular .180" walls. Maybe if your are lucky they will send the HD 3" OD .250" walls....or even better the 3.5" OD .50" wall(good luck with that though). As long as you get the .250" or greater I wouldn't worry about the 7k lb axles. Save your money. The axles are tested to 3X weight at speed. And all off-roading is done at slow speeds. I wouldn't worry about it.

I've just never seen a 5er toyhauler with a pin weight that low.
I had 1400lbs of Tongue weight on my 30' tow behind Weekend Warrior.
My pin weight on my 5er is 3400lbs when I am loaded up. Granted, I am 10' longer than you, but I don't have any slides on my trailer.

Thanks. Help me out some more...the 6k axles will have different springs than the 7k axles won't they? Presuming so, I'm thinking a 7k axle/spring setup will hold the trailer higher and stiffer.
Do you agree?

Springs and axles are spec'ed seperately. So I doubt they will send anything heavier than should have been on there in the first place.

That is correct.
This link will give some idea of the wide range of spring available for trailer applications
