Tremor Payload??

[Blitz]

Sorry for delay....life.

Here’s my sticker. I wanted to keep it pretty basic. My last truck was a F150 Lariat and I didn’t use much of the options. Didn’t want the 10000GVWR, but it was a compromise vs waiting to order.

Thanks! I missed the part where you said you had an F250, vs F350.

TOTAL NUMBERS:
2021 F350 7.3L Lariat (11300 GVWR)
Ultimate Package + Sport
Moonroof
5th wheel Prep
upfitters
Adaptive Steering / Cruise Control
Payload = 3751lbs
Firestone ride rite airbags w/airlift wireless one.

Here are my numbers with CAT scale weights. The first Cat scale is with the Tremor loaded without RV. Consist of 5 adults, full tank of gas, 5th wheel Demco Recon hitch installed, about 80lbs of miscellaneous tools, Viair 450P portable air compressor, Safe Jack recovery kit, extra 10 gallons of gas, extra 20lb propane tank....total weight=8520lbs.
The second Cat scale is with everything above plus the hitched 5er with camping gear also with portable 3650 Watt Firman generator loaded in front RV compartment. The Tremor sagged about 3 inches so I filled the airbags to 40lbs for a total sag of 1 1/2 inches.
The spreadsheet shows the calculations with the truck and truck/RV weight. With this load we were dry camping and I tend to pack a little more gear when camping w/o hookups.
As you can see, with a GVWR of 11300lbs, I am at 11420lbs (120lbs over payload capacity) even though I am below the max GAWR ratings on both axles and the truck GCWR. My pin weight is heavier than I expected. I will load the generator on the rear RV hitch to compensate next time.

Good data. I am in a circumstance where my truck cannot be stickered over a 26000 GCVWR unless I want to get a CDL, which I don't want. I will be towing commercial on occasion. As long as I stay within my weight rating (combined), I'm good.

Great little write up

WildWest - Thanks for these numbers. I see they calculated your actual pin weight at 2900 lbs. What is your RV's listed dry pin weight?

The website advertises the pin weight as 2180. When i took possession of the rig, the paper work said 2400. Now that it is loaded with camping gear, it's now at 2900. I can take at least 100lbs off the pin by mounting the generator at the rear.

Thanks again. I was curious if these RV manufacturers were anywhere close to their advertised pin weights. Sounds like in your case they were way off. But you're in good shape with just shifting the generator to the rear.

I haven't given this much thought at all - would the higher bed height of the Tremor wind up putting more weight on a 5th wheel pin?

At a quick thought, I wouldn't be surprised if it did increase pin weight.

If anything it’d lessen the pin weight and put more weight on the rear trailer axle

The “advertised”pin weight often does not include batteries or full propane tanks etc

If it’s lessening the load on the front axle the pin and the rear axle have to share that weight.

Not if the nose is higher up. It’s transferring weight to the back.
Nose down would be transferring weight on the pin

think of it like a balancing act

Think harder

I can’t think any harder. I smell smoke already

Think of a wheel barrow, as you lift weight off the legs it goes to both the handles and the wheel.

In this instance the handle is the pin, the legs are the front axle and the wheel is the rear axle.

The pin takes more weight and so does the rear axle

This conversation started out because someone mentioned the tremor being taller in the rear may increase the pin weight

the higher the nose goes up, the more weight is being transferred to the back of the trailer. Therefore taking weight off the pin.
is it easier to lift something that setting on the ground or is it easier to lift something that’s already off the ground?
At a certain point it’s going to tip back
Like a sea saw at a play ground

I already explained it, sorry you don’t get it

I'm with Jrod on this one. Raising the front end moves he COG of the trailer slightly higher and more to the rear which would decrease pin weight. the rear weight is centered over a virtual pivot point between the axles and may cause a different weight distribution between the axles but it isn't transferred to the pin.

Having said that, I suspect the difference in pin weight raising or lowering the front 4" would be almost negligible... although the weight split between the trailer axles could be affected.

Yup. And a wheel barrows tire is out past the load that it’s carrying A 5th wheels axles are almost in the center of the load like a sea saw. Not to mention that the truck is not lifting the weight of the pin. It’s simply supporting it.
