Dry camping is RV camping without electrical, water, or sewer hookups. You use onboard supplies and equipment instead. A campsite can be paid and developed and still be a dry campsite.
Make your first trip an easy one
For a first outing, choose one night close to home or a campground with a staffed office and an easy drive out. If possible, spend a practice night in your driveway without connecting shore power. Test the lights, refrigerator, water pump, toilet, and sleeping setup. You will learn more from that evening than from buying another accessory.
Write down your starting battery state of charge and tank levels. Check them the next morning. This gives you a baseline for your rig, rather than a promise based on somebody else’s equipment.
Plan around four limits
| Resource | What to check | Your next step |
|---|---|---|
| Battery power | Capacity, starting charge, overnight loads, and a charging option | Estimate battery runtime |
| Fresh water | Usable water, people, cooking, washing, and a reserve | Make a water budget |
| Waste capacity | Room in the gray and black tanks and a legal dump point | Plan the dump stop before departure |
| Time and conditions | Weather, access, site rules, and your exit route | Check the land manager’s information |
Understand what runs on your battery
Make a list of the things you expect to use. A light, water pump, furnace fan, and refrigerator controls may use the RV’s DC system. Household outlets may require an inverter when you are unplugged. Your actual equipment determines what works; a charged battery does not automatically make every outlet live.
Identify your refrigerator type. A compressor refrigerator and an absorption refrigerator running on propane have different electrical needs. Check the manual, then measure actual use if you can. Include devices that stay on overnight and the inverter’s own consumption.
Try the battery calculator with a low-solar scenario as well as your expected conditions. A heater fan running through a cold night or a shaded campsite can change the result significantly.
Budget water before you fill up
List drinking, cooking, dishes, handwashing, showers, and toilet use separately. Use your own measured amounts wherever possible. The water calculator lets you enter daily use and compare it with your remaining tank space.
Take a reserve that stays outside your normal daily budget. Check your loaded vehicle and axle limits before adding extra containers: water and equipment add weight. Keep potable-water equipment separate from waste-handling equipment.
Save water by shortening the time a faucet actually runs, washing a batch of dishes together, and fixing drips before departure. Do not reduce essential drinking water to stretch a trip.
Know your campsite before dark
Confirm that camping and vehicle access are allowed at the exact location. Review current closures and fire restrictions with the relevant land manager. Download the route and directions before cell service becomes unreliable. Choose a backup campsite so a full site or rough road does not force a bad decision.
A road shown on a map is not a guarantee that a large RV can turn around. Scout uncertain sections before taking your rig down them, and avoid arrivals after dark on a first visit.
Keep the first evening simple
- Park on an appropriate existing surface and set up according to your RV’s instructions.
- Record battery charge and tank levels before using water or appliances.
- Cook a meal you already know how to make with your off-grid setup.
- Check that your carbon monoxide and smoke alarms are working.
- Recheck supplies in the morning and adjust the next trip’s plan.
CDC guidance is to operate portable generators outdoors, more than 20 feet from windows, doors, and vents. Never run one inside an RV, tent, or enclosed space. Follow the generator manual and campsite restrictions, and consider neighboring campers’ openings too.
Leave with enough margin to get home
Set a turnaround point before your resources are exhausted. Leave before you reach your water reserve or equipment discharge limit. Keep RV wastewater onboard until you reach an approved disposal point. The goal of a first trip is a comfortable night and useful measurements—not a record for how long you can stay.

Common questions
Do I need solar to dry camp?
No. The requirement is enough usable stored energy for your trip and a suitable way to recharge when needed. Measure your use first, then decide whether solar would help.
Is dry camping always free?
No. A developed campground or event site can charge a fee while offering no hookups.
How many days can I stay?
There is no single answer. Your resource limits, weather, access conditions, and the location’s stay rules all matter. Use the calculators as planning estimates and keep a reserve.
