Winter RV camping in Pennsylvania.

The hardest part of winter RV camping in southwestern Pennsylvania is not the cold — it is finding somewhere open to plug in once the state parks close for the season. We run State Line Campground, a family-owned RV park sitting right on the WV/PA line in Blacksville, a short drive over the border from Waynesburg and Greene County, and we stay open 365 days a year. Here is what we tell RVers planning a Pennsylvania winter.

What winter is like in Greene County & SW PA

Around Waynesburg, winter highs usually sit in the upper 30s to low 40s°F with overnight lows down in the teens to low 20s, and January is the coldest stretch. Snowfall averages roughly 5 inches in December, 9 in January, and 8 in February — call it a couple of feet across a normal winter, though the year-to-year swing is huge, from barely 15 inches to over 70 in a heavy year. Local winters have actually trended a bit warmer and less snowy over the past decade, but you should still plan for routine sub-freezing nights.

Elevation is the thing to watch. The valleys around Greene County are relatively mild; the Laurel Highlands and Ohiopyle country to the east climb into the mountains and pick up a lot more snow and colder temperatures. State Line's spot down on the border is on the gentler, lower-snow side — but it is still a true four-season climate where your water lines freeze overnight if they are not protected.

Which Pennsylvania parks actually stay open

This trips up a lot of first-time winter campers. Most Pennsylvania state park (DCNR) campgrounds run a seasonal schedule — roughly the second Friday in April through mid-December — and close for the rest of the year. Ohiopyle's Kentuck Campground in the Laurel Highlands, for example, follows that seasonal window and shuts for winter.

The notable exception near you is Ryerson Station State Park, right in Greene County near Wind Ridge: its campground is listed as open year-round, with electric at many sites. The catches are real, though — winter access is not guaranteed in bad weather, the restroom facilities are reduced in the off-season, and like most public campgrounds the water system is typically shut off or limited once it stays below freezing. If you are counting on a public park, call it directly first; dates and winter services change year to year, and reservations run through visitPAparks.com or 888-727-2757. For a dependable, full-service winter base, a private year-round park with full hookups is the simpler answer.

Setting your rig up for the cold

Get these handful of things right and your rig stays comfortable well below freezing:

• Keep water flowing. A drinking-water-rated heated hose lets you stay on the spigot; otherwise fill the fresh tank and pull the hose off so nothing freezes in it overnight. The weak spot is the city-water inlet and the faucet riser — insulate both with foam covers or heat tape on a GFCI outlet.
• Protect the tanks. Fit thermostatic heater pads to the gray and black tanks, add some pink (non-toxic) RV antifreeze — never the automotive kind — and leave the dump valves shut until you actually dump, so no thin layer sits frozen in the line.
• Skirt the underbelly. Skirting is the highest-value cold-weather upgrade: it keeps wind out from under the rig and holds a warmer pocket of air around the plumbing. Just leave breather gaps for any combustion exhaust and keep an eye on trapped moisture over a long stay.
• Mind the propane. The furnace eats propane fast in real cold — expect to go through a 20-lb bottle every day or two when it is genuinely freezing (it depends heavily on insulation, wind, and your thermostat). Keep bottles full, and remember the furnace needs a healthy 12-volt battery to run its fan, so a dead battery means no heat.
• Manage moisture. Sealed-up rigs get damp. Vent a little — a cracked roof vent, the fan while cooking or showering — and steer clear of unvented "vent-free" propane heaters, which pump water vapor and exhaust straight into the cabin.
• Watch the batteries. Cold saps capacity. Keep them charged on shore power, and do not charge a lithium battery below freezing unless it is a self-heating model.
• Heat safely. An electric space heater on shore power (with tip-over and overheat shutoff) is the safe way to take load off the furnace — give it room, never leave it running unattended overnight, and keep a working carbon monoxide and propane alarm going.

Why full hookups win in winter

With the public campgrounds closed or watered-down for the season, the hookups are what let you actually camp. Electric runs your space heaters (which cut propane use dramatically), your tank and hose heaters, and keeps the batteries charged against the cold. A working water hookup means no rationing jugs, and a sewer connection keeps you from hauling to a frozen, closed dump station. At State Line every site is full 30 and 50 amp hookups, firewood is free and brought to your site, and the bathhouse has hot showers — all a short drive over the line from Greene County.

PennDOT rules and winter driving

A few Pennsylvania-specific things worth knowing before you tow a rig in winter:

• Storm vehicle restrictions. During winter storms PennDOT sets tiered restrictions on interstates and the Turnpike, and Tier 1 restrictions specifically prohibit RVs and vehicles towing trailers on affected roads until conditions clear. Check 511PA (511pa.com) for live restrictions before you set out.
• Studded tires are legal in Pennsylvania from November 1 through April 15; chains are allowed temporarily during snow and ice emergencies.
• Clear the snow off. PA law requires you to remove accumulated snow and ice from your vehicle — roof included — within 24 hours after a storm, so brush off the rig before you move it.

State Line is on 186 Cliff Rd in Blacksville, WV 26521, just across the line. Call ahead for directions from your route, or open the campground in Google Maps. On the West Virginia side of the line? See our guide to winter RV camping in West Virginia.
