Glamis / Imperial Sand Dunes RV Guide
Glamis is full off-grid desert camping on soft sand — no hookups, no assigned sites, and limited services once you’re in. Incredible trip when you plan water, power, and fuel correctly.
About Glamis (What it’s like)
The Imperial Sand Dunes (often called “Glamis”) are a massive off-highway recreation area where groups camp directly on the sand. There aren’t typical “campground sites” — you pick your spot, set up camp, and run off your own water and power.
Reality check: This is not hookup camping. Your comfort depends on how well you plan water, generator time, and fuel.
Campground Reality
- No hookups (no shore power, no water, no sewer).
- Soft sand access and parking—getting stuck is a real risk.
- Generator use is common (A/C and outlets need it).
- No on-site dump — you dump after you leave.
Good fit for:
- Dunes riders / groups
- Families who can conserve water
- People comfortable with generator use
What to Rent (This Matters Here)
Best overall: Toy Hauler
Purpose-built for dunes trips: generator use, high water demand, and hauling toys.
Purpose-built for dunes trips: generator use, high water demand, and hauling toys.
Other RVs that can work (with the right setup)
- Class C Motorhomes with larger fresh water capacity, an on-board generator, and inverter-supported outlets.
- Travel Trailers with larger tanks, solid battery banks, and generator support — lighter rigs generally do best in sand areas.
Important: Not all motorhomes or travel trailers are equal.
Glamis requires realistic water usage, generator planning, and conservative power expectations.
Water Planning
- Bring more drinking water than you think.
- Limit showers (quick rinse style).
- Use minimal-dishwashing habits.
- Plan for sand (you’ll clean more than normal).
Power & Generator Reality
- A/C requires generator—batteries won’t carry it.
- Run generator early to recover batteries.
- Keep loads reasonable when starting A/C.
- Plan quiet hours + etiquette with neighbors.
If something “won’t work,” it’s usually low voltage, GFCI, breaker, or an interlock. Use On-Trip Help.
Dump Plan (Before You Head Home)
- Expect full tanks after dunes weekends.
- Dump after leaving the dunes at a legal station.
- Never dump in the desert (serious fines + harm).
What Not To Do (Prevents 80% of Problems)
- Don’t run A/C nonstop without fuel planning.
- Don’t ignore low-voltage signs (sluggish slides/awning = charge needed).
- Don’t arrive late without a setup plan—sand setup in the dark is rough.
- Don’t leave with “almost full” tanks unless you know your dump stop.
Glamis FAQ
Is Glamis beginner friendly?
It depends. Glamis is full off-grid camping with no hookups. First-time renters can do it successfully
with the right RV and realistic expectations, but it’s more demanding than campground trips.
Do I have to rent a toy hauler?
Toy haulers are the best fit, but certain Class C motorhomes and well-equipped travel trailers can work
if they have sufficient water capacity, generator support, and strong battery/inverter systems.
Do I need a generator?
Yes. There is no shore power. Generators are required for A/C, outlets, and battery recovery.
How long do water tanks last?
It varies by group size and habits. With conservative use, many groups plan 2–3 days comfortably.
Long showers and heavy dishwashing will shorten that quickly.
Where do we dump tanks after the trip?
Dump after leaving the dunes at a legal dump station. Use our RV Utilities Guide
and plan your stop before you head home.
