Actual weight of my TM

[mjlaupp]

Jerry,

The GVAR sticker for my 2004 3326KD is:
GVWR 4916#
Front 3500#, 14 inch @ 50 psi.
Rear (no data).

Factory Options:
15,000 btu A/C (not low profile)
Electric tongue jack
Awning
Hanging cabinet
Amplified VHF/UHF TV antenna
Rear bike receiver
Magic Chef range (appears to be heavier than the Atwood)

It also has dual T105 batteries. I don't know if these were factory, dealer or owner installed. This year model has oak cabinets which may add some weight over what is installed now. Standard carpet interior.

Actual Weight of My TM-The latest revision-9/27/09

This attachment includes all of the information that I have so far. I will be at the Petaluma Rally and hope to gather more info there.

I will also be working on a simplified document. I like Bill's idea of splitting it into two pages.

Later,

Jerry

We just got back from our vacation. We stopped at a CAT scale and had the rig weighed. When we got home, I unhooked the trailer and weighed the tongue weight. Here's our results:

Front axle..........................3080#
Rear axle (incl tongue wt.)....3920#
Trailer Axle.........................3440#
Total rig...........................10,440#
Trailer tongue weight..............490#

Total trailer weight...............3930# Fully loaded (no water, 2-full propane tanks, 2-29 series Btrys))

Scale weight x2= tongue wt (minus 14# 7' long 2x12)

All weights are with TV and TM Connected:

TV Front Axle = 2420#
TV both Axles = 5380#
TV Back Axle & TM Axle = 6080#
TM Axle only = 3260#

Some day I want to get the weights on each side of the TM. I've had two blowouts and both were on the port side. I suspect the port side carries a heavier load. Consider the asymetrical weight that can be on the port side; 20 gal of fresh water, 6 gal of black water, six gal of hot water, Battery, Air Compressor, and I think the equipment weight of the Refrig, Water Heater, Toilet and Tub will outweigh the closet, cabinets and stove/oven.

Hope this info helps.

Did you happen to get your tongue weight?

Tongue Weight

Wayne - No I didn't get it at the time I did the other weights. I can weigh the tongue now and interpolate what it was with the TM loaded as before. Since the approximate wt is somewhere around 300-400# I should be able to get within 25#. I'll add that in tomorrow.

I was actually shocked that my tongue wt was close to 500#. I was VERY careful with my measurements and double checked everything several times (including calibrating the scale).

I weighed my 2720 from side to side. With no water in the fresh or gray tank, and the toilet empty, the starboard side was heavier by 40 lbs. I too thought that the port side would be heavier with all those items that you mentioned. But apparently the wood in all of those cabinets on the starboard side add up. The battery on the 2720SL is on the port side instead of on the tongue, which would add to the weight there on those models.

My weights with the WDH engaged were 1500 for the port side, and 1540 for starboard. When I added about 29 gallons of water to the TM (20 fresh, 6 hot water, 3 in the toilet) than that side should increase to about 1740 lbs.....close to the rated capacity of the 14" Marathons. Seems like a good reason that the port side tires would be the 1st to blow.

 

[PopBeavers]

Interesting idea about which side is heavier. I would expect my street side to be heavier, because I have the 40 gallon water tank and it is always full when I leave the house.

My one tire failure was on the curbside, opposite the heavy water.

My batteries are centered on the tongue.

Don;

Can you supply the information (if it is still in your TM) from the "as shipped" sticker inside the kitchen or sink cabinet door? It is sometimes called the CCC (Cargo Carrying Capacity) calculation sticker. It should state something like:

GVWR: the TM Gross Vehicle Weight Rating as designed
less UVW: the TM Unloaded Vehicle Weight as shipped with options
less 26 gal water: 216#
less 10 gal LP gas: 45#
equals CCC: the Cargo Carrying Capacity as calculated

I would like to add your TM data to the information I have been collecting for the TM actual weight data summary, if it is OK with you. Also, were most of the options you listed above installed on the TM when you bought it? Were they factory installed?

Sometimes the CCC is also listed on a sticker on the street side near the Gross Axle Weight sticker.

Thanks,

Jerry

Jerry,
This going to be a great database when you finish it. My weights on the 'as-shipped' sticker are as follows:

GVRW:............ 4217#
UVW:.............. 3213#
26 Gal. H2O:..... 216#
LP Gas 9.5 Gal.:...40#
CCC:................ 748#

You asked about my options. The following options from my list were not factory installed. These are my best guess for the weights of each:

Unmounted spare w/ tube:... 20#
Food Shelving Modification: ....2#
HDTV & Mount:...................... 5#
WDH - Equal-i-zer Brand:..... 92#
2 Folding Chairs:..................10#
1 Alum. Folding Table:............5#
Gear packed in TM:............. 300#
TOTAL:.............................. 434#

I hate to break this info up, but I have one more weight (tongue Wt.)coming which I won't have it till Friday.

How will we be able to access this data and when will you start making it available?

Don;

Attached is the latest revision to the spreadsheet (which includes your recent information) I'm still groping with the best way to display the data.

You can always find the latest revision by looking under the forum "General Discussions" at the thread title "Actual Weight of My TM" then click on the attachment symbol (paper clip). That will give you a list of all attachments. Look for the latest "TM GTWx" and click on it to open.

Eventually I think Bill will figure out a way to keep it in the reference library.

Thanks for your input. I hope I entered it correctly. I am awaiting your tongue weight and will enter that when it is available.

TV Front Axle = 2420#
TV both Axles = 5380#
TV Back Axle & TM Axle = 6080#
TM Axle only = 3260#

From this data I get that your GCVW (Gross Combined Vehicle Weight) is either 2420+6080 = 8500# or 5380+3260 = 8640#. I suspect the 140# discrepancy is the effect of the WDH and is an indication of the weight added to the TM axle by the WDH spring bar force.

Because of the way a WDH works, your actual axle weight measurements are biased in a way that adds more weight to the TV front axle, removes some weight from the TV rear axle and adds more weight to the TM axle.

The actual numbers can be figured out mathematically but we would need 1)the length of the TV wheel base, 2) the distance from the TV rear axle to hitch ball, 3) the distance from the hitch ball to the spring bar rear anchor points, 4) the distance from the TM hitch ball to TM axle and finally, the force of the spring bars pulling down on the TM frame.

This would allow us to calculate the lever arms (moments) and determine how much a weight is added to the TM axle.

Too much trouble IMHO but interesting to a geek like me as I play with the physics of trailer towing.

Jerry

Jerry,

I guess that you missed post #63. I added my actual weights.

Trailer Axle.........................3440#
Trailer tongue weight..............490#

Gross trailer weight...............3930#
(No WDH used)

My GTW from 2008 was 4103# but now I carry my generator, tables, matt, EZ-Up and chairs in the TV.

I sure did! Sorry!!! Now I wonder who else I missed.

Thanks for the Heads-Up.

Jerry:

I finally got around to weighing my tongue. It weighs 486# with the TM level and unloaded. Note that all other weights furnished were taken in the loaded condition.

Also, even with your explanation, I don't understand the 140# discrepancy. The weights were all taken as I moved from one position to another on the scales and, seems to me that the two scenarios would have to be the same. I think maybe the "weigher" rounded each figure slightly and the 104# is an accumulation of rounding. Note that the weigh slip was hand written and not stamped and certified.

Lastly, I like your starting spreadsheet, but I can see why you indicated you were struggling with it. You will almost have to specify how you want it weighed to minimize the type of data you receive.

Good Luck,

You bet we'll put it in the Library! This is exactly the kind of thing that belongs there, and this is a particularly valuable data base.

We'll put it in the Library whenever you are ready. However, once it is in the Library, it is harder to update - not impossible, just harder. Do you want to let it settle down a bit, both in format and in content, before we do it? Give me a ping whenever you are ready.

Good Luck,

Is your TM level when hitched? Seems to get a valid tongue wt. you have to have the TM in the same attitude as when hitched. So, however many inches your tongue is above ground on the hitch is where you need it to be when you weigh it.

When using the single scale and beam, the beam needs to be level, also, right? So the fulcrum point needs to be the same ht. as the scale on level ground. The tongue needs to be very centered between the fulcrum and the scale load point. And then you need to subtract 1/2 the weight of the beam.

I know the ideal attitude of the TM when towing is level, but if your setup is off level, you need to weigh it in that position.

Jim & Joan:
Thanks for checking me. The trailer hitch weight was with the trailer level. Also, when hitched to WDH the trailer is level.

I did use a fulcrum beam with single scale, except I call the point between the jack and the scale the fulcrum (pivot point). BTW, the weight only varied slightly when I jacked the beam higher than level, say 1/2 bubble would mean about 4-5#/2=2-2.5#.

I think the weight is good for publication.

Here is the latest version of the TMGVWR spread sheet.

It includes the recent posting by M&MHokie on the weights of their 2009.5 2720/Tundra combination.

Still haven't figured a way to simplify this thing.
