5.0 TA Pin Weight

Inside the closet wall is a "Vehicle Specification Nameplate". In regards to weights it shows the Tongue load range weight, GVWR and the Cargo Carrying Capacity.

Subtracting the C.C.C (1,001 lbs) from the GVWR (5,500 lbs) you end up with the U.V.W of 4,499 lbs.

The Tongue Load Range indicated by the 2017 E.T.I. Owners Manuel on page 14 is shown as 19% to 25%. On my trailer the 900lbs shown is 20% of the U.V.W.
This does not mean my pin was 900 lbs at delivery, merely indicating 20% of the U.V.W.
Once loaded with cargo, food, water one must weigh the trailer and distribute the load in order to achieve the 19% to 25% pin weight.


Chapter 3: Towing and Leveling.
It is an interesting read with a great amount of important information. E.T.I references 20% for the 5.0TA Pin Weight in several places.


GVWR (Gross Vehicle Weight Rating)
The maximum permissible weight of this coach when fully loaded. It includes all weight at the unit’s axle(s) and tongue or
pin.


UVW (Unloaded Vehicle Weight)
The weight of this trailer as manufactured at the factory. It includes all weight at the trailer axle(s) and tongue or pin. The UVW does not include cargo or fresh water.


CCC (Cargo Carrying Capacity)
This is the maximum amount of cargo you can safely add to this vehicle. Cargo carrying capacity is calculated with all manufacturer installed equipment, full propane tanks and full fresh water tank. We strongly recommend weighing your loaded RV prior to travel as described in this manual beginning on page 15 to ascertain you are within all weight limitations.

Happy Camping

If the Cargo Carrying Capacity is (appropriately) calculated with full fresh water tank and water heater, then the Unloaded Vehicle Weight is about 4299 pounds (since there is 160 pounds of water and 40 pounds of propane).

The 4299 pound value makes sense to me, since the base dry weight of a current 5.0TA is listed as 3885 pounds, and even 4299 pounds as-equipped and dry would imply 414 pounds in options on Tin's trailer.

The visible part of this form does not say whether or not fresh water is considered in the CCC calculation. Tin, do you also have a label like this one?

Minor notes:
  1. If Escape is going to use a typewriter which makes the same mark for the digit "1" and the lower case letter "l", they really should put a space between the value and the "lbs"!
  2. The numbered hitch classes defined by VESC V-5 and SAE J684 are only for ball hitches, not fifth-wheels. "Class 4 hitch" does not apply to a 5.0TA, although that is the right weight range.

Yes I have the "Transport Canada label" but honestly the number do not seem to add up ? also the wrong tongue/pin weight sticker was put on. When I asked at orientation they said they ran out of the right stickers.

The calculation on the sticker suggests
2500 kg GVWR - 127 kg freshwater - 27 kg hot water - 455 kg CCC = 1891 kg unloaded (presumably including 18 kg propane)

In pounds, that's
5500 lb GVWR - 280 lb freshwater - 60 lb hot water - 1003 lb CCC = 4157 lb unloaded (presumably including 40 lb propane)

1891 kg is not exactly 4157 lb, but there's some rounding going on here. Depending on which values you believe, that implies 272 to 284 pounds of options (and propane)

Also, sorry, but I didn't allow enough water weight in my earlier post... a combination of a typo in my calculations and the units of the tank volume (I assumed 28 US gallons and Escape is basing it on 28 Imperial gallons; I also forgot to convert from kg to lb).

Hi Brian B-P
I came across some of the same issues with conversion/rounding and just trying to figure out what is empty what is full and how escape incorporates these items to get there numbers. I did not even think about imperial gallons! so I learned something new .
I present the 3rd piece of the puzzle for you. (please note on E.T.I. check-off list under shipping the Lbs and KG are reversed)

Now that's a muddle of numbers. Aside from the kg/lb units being reversed, the label of "Cargo: Shipping: Pounds:" makes no sense (maybe it is supposed to be just cargo capacity and shipping weight, both in pounds?). The intent of the 4499 pound value is unclear; it is presumably the wet weight (GVWR less CCC; or unloaded weight plus freshwater, water heater contents, and propane).

I just checked my sticker because I seem to remember reading that it said the same 10-15 not 20 percent.

Guess they were out of stickers for a while. Our 5.0TA was built in Sept. 2016 four months before yours.

Hi emers382
Well at least I was not the only one.

Where are just a couple snipets from 201 7 owner manual Chapter 3 (which is on E.T.I. website in PDF form) if anyones interested.

I think it's strange that they advise that the waste tanks should be empty, since they are ahead of the axle and low (although the black tank is a bit higher than grey)... the location of their mass improves stability if anything, although sloshing can be bad. At the same time, they don't mention keeping the fresh tank empty, but it is behind the axle so greater mass there hurts stability.

If the trailer was within GVWR and stable with fresh water and no waste, it will still be within GVWR and more stable with the water moved to the waste tanks.

There are two things to consider:

1. Dynamic Loads vary, but they can have a significant effect on stability. This constantly changing load makes the trailer move. If the dynamic load is small compared to the weight of the trailer, it may not be important, but if the moving load is a large, the effect is significant.

2.Center of Gravity is three dimensional. side to side, front to back and top to bottom.
Driving with empty tanks would be great but impracticable.
If are travel destination is let say 2 or 3 days drive, I normally will fill my fresh tanks 1/4 and fill it up on arrival. How ever if we are Boon-docking locally then I drive with full fresh tanks.

True. The same for propane. And the water (whether as fresh or waste) is about 5% of the trailer mass at most - we're not talking about tanker trucks here.

Agreed. Both fresh and grey tanks are basically central left-to-right, located between the frame rails; the grey tank is lower. The black tank is higher, and far off to one side in all but the 21'... but it's also smaller and well forward.

With our Escape-like trailer I similarly avoided a full water tank, but it's a hassle if camping anywhere that does not have a fresh water supply... and who wants to drain extra from the tank if leaving somewhere without having used everything in the tank? With our current motorhome I just fill the fresh tank when water is available. Fresh water becomes waste water, so if waste (at least grey) is dumped whenever fresh is added, total water mass (versus GVWR or as a dynamic load) isn't an issue.

I agree with you, the only reason it may be there is in a real world dog wagging the tail situation. Can you imagine the forces applied going down the road with lets say 100 Lbs in each tank doing 70 mph when the wag starts. Now that would be interesting! I don't know about you but that is even more reason to have the proper pin weight and avoid the the whole mess to begin with. IMO
