Dry Weight v.s. Weight with Full Tanks and/or Gear in a Motorhome
Dry weight is the weight of a vehicle without any passengers, consumables, or cargo. When it comes to RV's, dry weight is calculated with empty tanks. So, once you fill-up the tanks with water, that's additional weight to your RV, even before you load it up with gear and passengers.
Recreational vehicles usually come with three tanks that can be found on the underside of the RV. The three most common tanks are freshwater, greywater, and black water tanks. The freshwater tank stores the RV's drinking water supply, when not hooked up to a City Water source. The gray water tank holds the used water from the shower and sinks. Many older RV's will not have a gray water tank. Finally, the black water tank contains used water from your toilet (basically, sewage). If an RV does not have a gray tank, then all dirty water is sent into the black water tank.
The contents of these tanks are not taken into consideration when discussing a motorhome's dry weight. In larger rigs, these tanks can hold quite a large volume of fluid and may contribute significantly to the final weight.
Floorplans matter
If you have your heart set on a particular motorhome model and are looking to find out its weight, pay attention to the floorplan. Most RV models come with a variety of floorplans to choose from. The floorplan you choose can affect the dry weight of your motorhome too. That's because some floorplans have more furniture and appliances than others.
How much does Class A motorhome weigh?
Shaped like a huge greyhound bus, Class A motorhomes are the largest of all motorhomes and so the also weigh the most, on average.
Most Class A motorhomes weigh between 16,000 and 30,000 pounds. The weight will be significantly larger or smaller for different models and makes.
Class A motorhomes are also the longest ones. The majority of the Class A motorhomes have lengths that range from twenty-one feet up to forty-five feet. Class A motorhomes are around thirty-three feet long on average and are around ten feet high on average. Class A motorhomes have an average width of 9.5 feet. They typically need a bigger than average garage for storage. A garage would need an average height of at least fourteen feet or more and length that is bigger than forty-five feet.
Class A's are like houses on wheels. They can be simple or complex. Some include luxuries like washer and dryers, king-size beds, and mobile garages that can hold a car. They often have slide-ins that increase the motorhome's volume and overall weight.

How much does a Class B Motorhome Weigh?
Also known as van conversions, Class B motorhomes are the smallest of the three Classes so it makes sense that their weight is also the lowest of the Classes.
Most Class B motorhomes weigh between 4,000 and 14,000 pounds. They are the size of a large full-size van and are as high and wide as one. Usually designed for two people, these motorhomes can accommodate up to four and even six people, depending on the specific model and floorplan.
The biggest disadvantage of owning a Class B motorhome is that you do not get as much space. Also, there are fewer luxuries in Class B motorhomes compared to Class A's and C's. However, Class B benefits include that they get good fuel economy, can stay off the grid, come in a 4x4 option, can fit in most parking spots, and they are relatively easy to drive.

We appreciate the information, Harry!
Yes, anything added costs some weight. Sometimes we forgot how heavy all the liquids are. I stumbled upon a site that calculates the loads I put on my motorhome and checks the overall weight. I am not sure it would close-enough estimate or not but it was interesting.
