GVW= Gross Vehicle Weight
GVWR= Gross Vehicle Weight Rating
In simple terms;
GVW is the weight of the vehicle alone
GVWR is the maximum weight the vehicle is rated to weigh.

As an aside, GCVWR (Gross Combined Vehicle Weight Rating) is the maximum weight of vehicle and any towed vehicles, of which neither should exceed the recommended GVWR respectively.

Spence is correct as far as I know.

Here's the RVIA's list of weight terms...lots of different terms, like I found it interesting that to figure CCC the RVIA discounts a full tank of propane:

Hey, thanks for the info, so how do I determine the GVW of a motorhome? The reason I am asking this question is in South Carolina the term GVW is used to determine if a special drivers license is needed. SC law states if the GVW is 26,000lbs or more a special class E or F depending whether towing or not. I have been keeping this in mind when looking for the motorhome I want to purchase. The trouble is the GVW is not listed in the specs. It's always GVWR.

The GVW of every vehicle can be different as it's the actual weight of the vehicle.

You will have to weigh the MH to know the GVW.

You might double check the license requirements as it's usually the GVWR that determines the drivers license requirements.

I'm not SURE about SC requirements, but in many states the requirements for a "special" license, based on GVWR, only apply to COMMERCIAL vehicles. You "may" not need a special license for recreational driving.

Some states DO require an "endorsement" for air brakes, even on non-CDL licenses.

Good luck finding a coach of your dreams!

Good information, and not to be picky, but we don't want to confuse the OP...the correct acronym is GCWR.

Right - GCWR (Gross Combination Weight Rating) - the maximum rated weight of the vehicle + any towed load

From the SC DMV website, they base the license requirement on GVW and define that as:
Gross Vehicle Weight (GVW): The empty weight of a vehicle plus the weight of its load in addition to the empty weight of a towed unit and its load weight.
They also define GVWR and kinda smush GVWR and GCWR together there also.
Info is here: SC Department of Motor Vehicles

For the OP, although based on actual weight, to avoid needing a different license for the occasion you are heavily loaded, if your GVWR exceeds 26000 just get the class E or if you will also be towing a trailer or TOAD the class F. Wow!!!

Technically, if stopped they would have to weight your vehicles to see if you comply..

Also notice the class E or F license specifically does not allow you to operate a 2 wheel motorcyle with a sidecar.

Often there is a piece of paper located behind a wardrobe door or something that will have the MH's dry weight or unloaded curb weight etc. Add to that whatever you will tow and bring in the MH although I'm not sure how much they will care about anything but the curb weight and towed vehicle.

INTERESTING. I always used GCVWR, thinking Gross Combined Vehicles Weight Rating.

You say ToMatoe, I say TomaToe comes to mind....

I'm betting different States use different strokes, too.

Ed,

From Section 522.003 of the Texas Transportation Code:

Quote:
(17) "Gross combination weight rating" means the value specified by the manufacturer as the loaded weight of a combination or articulated vehicle or, if the manufacturer has not specified a value, the sum of the gross vehicle weight rating of the power unit and the total weight of the towed unit or units and any load on a towed unit.

(18) "Gross vehicle weight rating" means the value specified by the manufacturer as the loaded weight of a single vehicle.
Does Louisiana not use similar terminology and definitions? Or are you in Mississippi now?

Rusty

I'm live in MS now, and I have not needed to know what they require.

Please say "HI" to Sandy!
