Two Ways to Spend a Desert Winter

Start with how long you want to stay in one place, because Arizona's public campgrounds set limits:

• Arizona State Parks cap stays at 14 nights within a 30-day period per park, per household, though a park manager can extend that (Arizona State Parks reservation policies). A state park works well as a week or two on your route, not as a season-long base.
• Bureau of Land Management (BLM) dispersed camping is generally limited to 14 days within any 28-day period. Then BLM says to move, often at least 25 to 30 miles; limits vary by field office (BLM camping).
• BLM Long-Term Visitor Areas (LTVAs) are the public-land option built for snowbirds. With a permit, BLM says winter visitors may stay up to seven consecutive months.
• Private RV resorts and parks set their own terms. A season-long site depends on the operator's agreement for your dates and your RV.

Desert Boondocking: What the RV Has to Carry

La Posa LTVA, with entrances about 2 miles south of Quartzsite off Highway 95, and Imperial Dam LTVA, north of Yuma on the California side of the Colorado River, are both managed by BLM's Yuma Field Office. According to BLM (La Posa LTVA and the LTVA supplementary rules):

• A permit is required from September 15 to April 15. As of November 2026, BLM lists a $180 long-term permit for the whole season or any part of it and a $40 short-visit permit for 14 consecutive days, which can be renewed. Either permit is valid at every BLM LTVA.
• The facilities are shared, not hookups. La Posa lists vault toilets, water faucets, dump stations and trash service. BLM doesn't list electric, water or sewer connections at individual campsites, so don't plan on them.
• La Posa and Imperial Dam require self-contained RVs, except within 500 feet of a vault toilet or restroom. BLM counts an RV as self-contained only if it has a permanently installed wastewater holding tank of at least 10 gallons. Portable toilets and portable holding tanks don't qualify.
• The RV must stay mobile. Wheels stay on, camping units must be at least 15 feet apart and a camp can't be left unoccupied for more than five days without BLM approval.

What that means for the RV:

• Your tanks set the rhythm of the winter. Fresh, gray and black tank sizes decide how often you visit the faucet and dump station. Capacity doesn't tell you how many days a tank lasts, so track your own use on a short trial stay. Water weight also counts against cargo capacity.
• Check the waste setup on a camper van. If you're considering a Class B for LTVA stays, confirm it has a permanently installed holding tank that meets BLM's definition.

Strong fits: a travel trailer or fifth wheel with generous tanks, propane capacity and room for battery and solar equipment, left at camp while the tow vehicle makes supply runs; a Class C for travelers who'd rather not tow; or a Class B for couples who move often and accept smaller tanks and living space. Larger motorhomes can boondock too; size tanks and power the same way. Our boondocking guide covers site choice, water and waste in detail.

Resort Basecamp: What the RV Has to Live Up To

Months on one site with hookups make daily comfort the priority.

Strong fits:

• A larger travel trailer for a balance of space and a wider range of tow vehicles
• A fifth wheel for generous living space and storage, with the pickup doubling as your daily vehicle
• A destination trailer if you'll park for the season and move rarely. These are designed for extended stays rather than frequent travel, so plan how you'll move it to Arizona and back; see our destination trailer overview.
• A Class A for one vehicle with generous living space, plus a towed car for errands

What to check:

• A kitchen, living area and seating you'll be happy using through long winter evenings
• Storage for a season's clothes, including warm layers for desert nights
• Whether the RV is built for 30-amp or 50-amp service, and which the resort provides at your site
• Site length, slide-out clearance and room for a second vehicle
• Whether the park has rules about the RV itself, such as its type or age
• Extended-stay use. Read the exact RV's manual and warranty for continuous-occupancy limits. A park's seasonal reservation does not establish that the RV is designed for that use.

A resort winter can still include a week at a state park. Catalina State Park near Tucson lists 120 sites with water and 20/30/50-amp electric and no limit on RV length (Catalina State Park). Lost Dutchman State Park, about 40 miles east of Phoenix, lists 68 sites with electric and water and no size restrictions on RVs (Lost Dutchman State Park). The 14-night limit still applies. For life in one spot, see our guide to stationary RV living.

Power, Solar and Generator Hours

BLM describes La Posa as flat and sparsely vegetated, so shade rarely limits solar there. The season does. Winter days are the shortest of the year, and the furnace works hardest at night, when panels produce nothing. Plan power for the long, cold night, not a sunny afternoon.

Generator rules can be tight:

• At Organ Pipe Cactus National Monument's Twin Peaks Campground, the National Park Service lists generator hours of 8 to 10 a.m. and 4 to 6 p.m., and generators are prohibited in sites 113–208 (NPS Twin Peaks). That's four generator hours a day at most.
• In the LTVAs, quiet hours are 10 p.m. to 6 a.m. unless posted otherwise, and BLM prohibits running generators in a way that makes unreasonable noise.

If you'll camp off-grid, list what runs overnight, such as the furnace fan, refrigerator, water pump and any medical device you rely on. Then ask the dealer which of those the installed battery and inverter support and for how long, and what solar and generator equipment or prep the exact unit has. Our RV electrical systems guide and RV solar guide explain how these pieces work together.

Cold Desert Nights

The National Park Service says winter overnight lows at Organ Pipe Cactus can fall into the 30s (NPS Organ Pipe weather). At Catalina State Park near Tucson, Arizona State Parks says January and February lows can drop below freezing, occasionally into the teens, and that a 40-degree swing between the day's low and high is not uncommon in winter (Catalina weather).

At a resort, shore power runs more of the heating and tank-protection equipment. Off-grid, propane and batteries carry it. In one current towable owner's manual, for example, the furnace runs on both propane and 12-volt power, and the manual notes that more furnace use raises both battery draw and propane consumption. The same manual says its 120-volt tank heaters work only on shore power or a generator, leaving just the 12-volt heaters otherwise.

Before you buy, ask how the furnace is powered, how many cold nights the propane supply covers at your usage and what heat protection the tanks and plumbing have. Ask, too, what cold-weather features the manufacturer documents for the exact unit. That same manual calls for testing the carbon monoxide and propane alarm before each trip and weekly while in use.

Getting there can mean crossing high country. The National Park Service says Walnut Canyon, near Flagstaff, can see heavy snow in winter and early spring (NPS Walnut Canyon weather). Our RV heating systems guide covers how RV furnaces work.

Dust, Dirt Roads and Rig Length

Don't assume desert campgrounds share one length rule. Catalina and Lost Dutchman list no RV length limit. Twin Peaks has 174 RV sites, but the National Park Service describes only a few as large enough for RVs up to 45 feet. A big rig welcome at one campground may have few sites at another, so check the specific site before you book. For destination planning, see the Organ Pipe section of our winter national parks camping guide.

On public land, BLM requires entering La Posa only on legal access roads along Highway 95, sets a 15 mph speed limit in the LTVAs unless posted otherwise and prohibits overnight camping in desert washes at La Posa and Imperial Dam. Dispersed sites elsewhere may be reached on unpaved roads; scout them in daylight and stay within what the RV manufacturer permits.

Dust is daily housekeeping, so check the door and slide-out seals and favor flooring that's easy to sweep.

Towable or Motorhome for a Desert Winter?

A towable stays parked while the tow vehicle handles groceries, propane and trailheads. A fifth wheel needs a pickup with a fifth-wheel hitch; our travel trailer vs. fifth wheel guide compares the two.

A motorhome skips the hitching at each stop, which suits a mobile winter. Without a towed car, though, every errand means packing up camp. Arizona State Parks doesn't charge its extra-vehicle fee for a car towed behind an RV when the RV stays at the site and the car is used for transportation. See our Class C vs. Class A guide.

Two Sample Arizona Winters

A couple's resort season. Picture a retired couple spending January through March at an RV resort outside Phoenix. A fifth wheel gives them a full kitchen and room for visiting family, and the pickup handles errands. Before buying, they confirm the resort's site length, slide clearance and electrical service. They add two week-long side trips to state parks, each well inside the 14-night cap.

A mobile desert winter. Now picture two retirees spending December through February on public land. They start on a short-visit permit at La Posa, book two weeks at Twin Peaks, where generator hours are limited, spend a week on shore power at a state park, then return to an LTVA on a long-term permit. A travel trailer with large tanks, solar and ample propane fits that plan, with the tow vehicle for supply runs. Before buying, they check how many days the tanks last for two and whether the battery carries the furnace through a cold night.
