I want to find out what the Actual combined weight of my truck and trailer is fully loaded. I bring a lot of 'stuff' when I camping. Where can I go to weigh my rig? Anyone know if the Highway Patrol will allow me to weigh in at one of their big-rig weigh staitions? My local phone book has no listings under 'public scales'.

How to weigh your travel trailer
To properly weigh a travel trailer, it should first be weighed, including the tongue weight, while detached from the pulling vehicle. This actual overall weight must be less than or equal to the GVWR for safe operation.

If the overall weight is greater than the GVWR, some contents must be removed until maximum GVWR limitations are achieved. Once the actual overall weight is determined and the trailer is within GVWR limits, the following weights must be determined:

1. Weight of complete trailer, while attached, but excluding towed vehicle. This will result in the actual weight which is exerted on all of the trailer tires. This weight may be subtracted from the overall trailer weight (above) to determine actual "tongue" weight.

2. With the trailer still attached to the towed vehicle, each wheel position should then be weighed separately to be sure each tire is not overloaded. If and overload condition exists on any wheel position, trailer loading must be redistributed or removed. If an overload situation is not corrected, tire or mechanical failures may occur.

3. The individual wheel positions (particularly the rear positions) on the towing vehicle should also be weighed for possible overload while the trailer remains attached. This is especially important on 5th-wheel applications where tongue weight may be extreme.
Remember that the GCWR includes the weight of everything--your tow vehicle, trailer, tool box, trailer hitch, fresh water, food, passengers, camping equipment, firewood, clothing and even kids toys. If the total weight of your rig is higher than the GCWR, then put the rig on a diet

DW -- Dry weight. The manufacturer's listing of the approximate weight of the RV with no supplies, water, fuel or passengers.

GAWR (Gross Axle Weight Rating) -- The manufacturer's rating for the maximum allowable weight that an axle is designed to carry. Gawr applies to tow vehicle, trailer, fifth-wheel and motorhome axles.

GCWR (Gross Combination Weight Rating) -- The maximum allowable weight of the combination of tow vehicle and trailer/ fifth-wheel, or motorhome and dinghy. It includes the weight of the vehicle, trailer/fifth-wheel (or dinghy), cargo, passengers and a full load of fluids (fresh water, propane, fuel, etc.). GTWR (Gross Trailer Weight Rating) -- Maximum allowable weight of a trailer, fully loaded with cargo and fluids.
Back to the top

GVWR (Gross Vehicle Weight Rating) -- The total allowable weight of a vehicle, including passengers, cargo, fluids and hitch weight.

Will ride,
I went to Atlas Van Lines, and they have their own scale to weigh the trucks. Check with some of the moving companies, to see if they have a scale. You can also contact a lot of the recycling centers. They have scales too. Sometimes you local dump has scales you can weigh on. It should be around $10.00 bucks.

More than you ever wanted to know about weight

Base Curb Weight - The nominal weight of a vehicle with standard equipment and a full tank of fuel. It does not include passengers, cargo or optional equipment.

Cargo Weight - Includes all weight added to the base curb weight, including passengers, cargo and optional equipment. Trailer tongue weight is also part of the cargo weight when towing.

Gross Vehicle Weight (GVW) - The actual weight of the vehicle when fully loaded. It is the base curb weight plus the cargo weight.

Payload - The combined, maximum allowable weight of cargo, occupants and optional equipment that the vehicle is designed to carry. (Gross Vehicle Weight Rating minus the base curb weight.)

Gross Vehicle Weight Rating (GVWR) - The maximum allowable weight of the fully loaded vehicle.

Gross Combined Weight (GCW) - The actual weight of the vehicle and trailer combined. This weight should always be obtained by weighing the vehicle and trailer together on a scale.

Gross Combined Weight Rating (GCWR) - The maximum weight of the towing vehicle and the loaded trailer - including cargo and passengers.

Maximum Loaded Trailer Weight - The maximum allowable fully loaded weight of the trailer. This weight is obtained by subtracting the towing vehicle's GVW from its GCWR.

Gross Axle Weight (GAW) - The total weight supported by each axle (front or rear). To compute this weight for your vehicle and trailer combined, take the loaded vehicle and trailer to a scale. With the trailer attached, place the front wheels of the vehicle on the scale to obtain the front GAW. To obtain the rear GAW, weigh the towing vehicle with the trailer attached, but with just the four wheels of the vehicle on the scale. The rear GAW is determined by subtracting the front GAW from that amount.

Gross Axle Weight Rating (GAWR) - The total weight each axle is capable of carrying. The total load on each axle must not exceed its GAWR
========= ==================================
Where to weigh your RV/Travel Trailer
To weigh your RV correctly, measure the fully loaded vehicle, axle by axle and wheel position by wheel position. you can find several certified public or commercial scales at moving and storage lots, farm suppliers with grain elevators, gravel pits, recycling companies, and large commercial truck stops. (Also look in the telephone book under "weighers" or "weighing.") Allow adequate time, since the entire weighing process can take up to 30 minutes. There may be a small fee for each weight taken, but the expense is a worthwhile investment towards the safe and economical operation of your vehicle.

There are three types of scales:
1. PLATFORM - This scale is long enough to weigh the complete vehicle. The following steps are suggested:
a. Pull onto the scale so that only the front axle is on the platform (with the end of the scale midway between the front and rear axles), and record the scaled weight.
b. Pull forward until the full unit is on the scale weight.
c. Pull forward so that only the rear axle is on the scale (again with the edge of the scale midway between the front and drive axles), and record the scaled weight.
d. If the RV has a rear tag axle, pull forward so that only the tag axle remains on the scale, and record the scaled weight.
If there is no towed vehicle, this weight will represent the actual weight on the tag axle. To determine the actual load on the drive axle, subtract this value from the recorded weight in step 1c. If there is a towed vehicle, proceed to step 1e to obtain the "towed vehicle only" weight. Subtract that value from the value above and then subtract that from the weight recorded in step 1c.
e. If a boat, trailer or other vehicle is being towed, it should be weighed and combined with the towing vehicle's GVW to ensure the total weight does not exceed the GCWR.

2. SEGMENTED PLATFORM - Platform scales with segmented sections can provide individual axle weights and total vehicle weights simultaneously, when the vehicle is positioned properly.
TYPICAL "other weights to be added in or subtracted
Fresh Water Tank @ 8.3 lbs/gal.
Gray Water Tank @ 8.3 lbs./ gal
Black water Tank @ 8.3 lbs./gal
LPG Tank (Wet Cap.) @ 4.5 lbs./gal
Gasoline @ 5.8 ~ 6.5 lbs./gal [RV & Electric Generator]
Deisel fuel @ approx. 7lbs/gal [RV & electric generator]
