RV packing and weight comes down to four things you should be able to say out loud: what your rig is rated for, what it weighs empty, what it weighs loaded the way you actually travel, and where that load sits. Those numbers come off your own weight placard and your own trip to a scale. Once you have them written down, packing becomes arithmetic instead of guesswork.
This article is about knowing and recording your numbers. It is not about towing. Weight ratings, how they apply to your specific rig, hitch selection and setup, braking and the act of towing itself are governed by your manufacturer's manual and belong with a qualified RV technician or your dealer. Do not take a rating, a figure or a setup from an article, a forum or a neighbor at the campground.
Why RV packing and weight is a planning problem
Weight gets treated as a driving topic, which is why it goes wrong. By the time you are on the road, every decision that determined the load was made days earlier in a driveway.
Three things make it sneak up on people. Water is heavy, and whether you travel with tanks full or empty changes the picture completely. Consumables accumulate across a long trip faster than anyone expects, so the rig that weighed in fine in week one is a different rig in week four. And gear acquired mid-season never gets weighed, because it arrives one item at a time.
The remedy is boring and it works: get real numbers once, keep a running list of what you carry, and re-weigh after any change in how you travel.
Read the weight placard before you pack anything
Every RV carries a label, usually a sticker or plate, with its ratings and capacities. Find it before you plan anything. It is commonly on the outside near the front on one side, or inside a storage compartment, or near the entry door, and your manual says exactly where.
Then learn what each term on it refers to, because they are not interchangeable and people routinely compare the wrong two.
| Term | What it refers to |
|---|---|
| Gross vehicle weight rating | The maximum the manufacturer rates for that single vehicle, fully loaded |
| Gross axle weight rating | The maximum rated for one axle, stated separately for each axle |
| Gross combination weight rating | The maximum rated for a tow vehicle and what it tows, counted together |
| Unloaded or dry weight | What the unit weighed as built, before you added anything |
| Cargo carrying capacity | What the manufacturer says you may add — gear, water, propane, people, everything |
| Tongue or hitch weight | The portion of a trailer's weight carried at its connection point |
Copy your rig's figures off the placard into your trip binder in your own handwriting, with the date and where you found them. Photograph the placard too. Placards fade, get painted over and get covered by a later sticker, and you do not want to be reconstructing this from a brochure.
If any term on your placard is unclear, or the figures do not seem to agree with each other, that is a question for your dealer or a qualified RV technician, not something to interpret yourself.
What to weigh, and where
A placard tells you what you are allowed. A scale tells you what you have. You need both, and only one of them can be found in a driveway.
Weigh the rig the way you travel. That means fully loaded with the gear you actually carry, the fluids at the levels you actually travel with, and the people and pets who are actually aboard. A weigh-in done empty tells you almost nothing useful.
What is worth measuring, in increasing order of detail:
- Total weight. The whole thing, as loaded. The baseline number.
- Axle by axle. Separate figures for each axle rather than one total, which is where imbalance shows up.
- Side to side. Left and right separately. A rig can total out fine and still be loaded unevenly, and a total weight hides it completely.
- Wheel position. The most detailed version, available at specialized weighing services and some RV events.
Public certified scales at truck stops and agricultural facilities handle the first two. Call ahead to ask how they want you to approach and position, because procedures differ by location, then follow the attendant's instructions rather than improvising on the pad.
Record the results with the date, the conditions, what was aboard and the fluid levels. Then re-weigh when something material changes: a new season of gear, a longer trip, a different towing arrangement, or a full-time setup replacing a weekend one. A weigh-in from three years and two seasons of accumulated stuff ago is a historical document.
How RV packing and weight gets distributed in the rig
Totals are half the question. Where the weight sits is the other half, and it is the half people skip.
Four principles cover ordinary loading:
- Low beats high. Heavy things belong as close to the floor as they can get. Weight carried up high behaves differently from weight carried low, and overhead cabinets are the wrong home for anything dense.
- Center beats ends. Keep heavy items near the middle of the rig and near the axles rather than piled at the front or hanging off the back.
- Balanced beats convenient. Resist loading everything heavy onto the side with the big door or the biggest compartment. Spread it, then verify it with a side-to-side weigh-in rather than by eye.
- Secured beats stacked. Anything that can move will. Strap, wedge or block heavy items so they stay where you put them, and fill empty space rather than leaving a heavy item room to travel.
What the manufacturer specifies about distribution for your particular rig overrides every one of those, and anything to do with the connection between a tow vehicle and a trailer — hitch type, setup, adjustment, weight transfer — is manual-and-technician territory without exception. There is no general advice worth taking on that subject.
A packing list method that keeps RV packing and weight honest
The method is a written inventory organized by category, with a weight column, kept between trips. It sounds tedious and it takes one afternoon, once.
Build it like this:
- Empty the rig completely. Everything out, onto a driveway or a garage floor. You cannot inventory what you cannot see.
- Sort into categories. Kitchen, bedding, clothing, tools, outdoor gear, maintenance supplies, safety equipment, entertainment, documents.
- Pack each category into its own labeled bin and weigh the bin on a bathroom or luggage scale. Write the figure on the list next to the category.
- Add the fixed items you cannot bin — chairs, mats, hoses, blocks, tools — and weigh those individually.
- Note what you did not use last trip. Everything you carried and never touched. This is the single most productive column on the list.
- Cut from that column first. If you cannot name the specific trip or situation that needs an item, it comes out.
- Apply one in, one out. Anything new that comes aboard displaces something, and gets weighed and added to the list the same day.
- Keep the list in the trip binder with the weigh-in results and the placard figures, so all your numbers live in one place.
Re-run the full version once a year and the quick version — the unused column — after every trip. That habit alone keeps a rig from drifting heavier every season, which is the way it usually happens.
Where this stops and a professional starts
Be clear about the line. Writing down what your placard says, weighing your rig, recording the results and deciding what you carry are all yours to do.
Interpreting whether a particular combination is appropriate, selecting or setting up a hitch, adjusting brakes, modifying suspension or anything to do with how the rig drives and stops is not. That is work for a qualified RV technician or your dealer, with your manual as the reference. Bring your weigh-in slips and your placard figures to that conversation — they make it a short one.
Know your numbers, write them down, weigh the rig loaded as you travel, and keep an inventory that cuts itself back. For printable packing inventory sheets with a weight column and a place to record your placard and weigh-in figures, visit the Free Guides page.
