When to Winterize Your RV in Camden, NJ

ON TRACK141 days until first 28°F freezeNov 29

Aim to winterize your RV in Camden by November 19, roughly a week and a half before the median first 28°F freeze of November 29, which one fall in ten shows up by November 12. Cold deepens quickly here — only about 12 days separate the first frost from that hard freeze.

NOAA station: Phila Franklin Inst · 3.6 mi away · 60 ft elevation.

Camden draws its numbers from Phila Franklin Inst, 60 feet up and 3.6 miles away. Its median first-freeze dates are 32°F by Nov 17, 28°F by Nov 29, 24°F by Dec 14. That hard freeze has landed anywhere from Nov 12 to Dec 18, a swing of roughly 36 days. Spring's last 32°F freeze clears around Mar 30. Snowfall averages 16 inches a year, first reaching an inch near December.

The freeze arrives in two steps in Camden: 32°F around Nov 17, then a hard 28°F near Nov 29. That first freezing night has ranged from Nov 4 to Dec 4, roughly a 30-day spread. On the spring side, the last 32°F freeze clears around Mar 30 and as late as Apr 12 — the green light for reopening water and de-winterizing. With around 16 inches of snow annually, plan for a handful of plowable storms each winter.

Your rv checklist

  1. Drain the fresh, gray, and black tanks, then drain the water heater only after it has cooled and lost pressure.
  2. Bypass the water heater so you do not waste six gallons of antifreeze filling the tank.
  3. Blow out the lines with a compressor at about 30–40 psi, then pump non-toxic RV antifreeze through every faucet until it runs pink.
    Helpful gear: RV antifreeze (6-pack) — Recommended pick
  4. Use a water-pump converter kit to draw antifreeze straight from the jug through the plumbing.
    Helpful gear: Water pump converter kit — Recommended pick
  5. Pour a cup of antifreeze into each drain trap and the toilet to protect the seals.
  6. Fit a blow-out plug at the city-water inlet so you can clear that line too.
    Helpful gear: Blow-out plug — Recommended pick
  7. Remove batteries or put them on a maintainer, and store them off a cold concrete floor.
  8. Cover roof vents, close the propane, and set out traps or deterrents so mice do not move in.

What this means locally

Compared with nearby cities, Camden's first-freeze date near Nov 29 sits close to Philadelphia (Nov 29) and later than Wilmington (Nov 15). New Jersey's deadlines span Oct 28 to Nov 22 statewide — one date for all of New Jersey would be off by weeks for Camden. Once you know Camden's freeze date, use it to shut down your sprinklers and winterize a boat too.

Frequently asked questions

At what temperature do RV pipes freeze?
An RV's exposed plumbing and thin-walled tanks can begin to freeze once temperatures sit in the mid-20s for a few hours, sooner than a house because there is little insulation around the lines. That is why the winterizing deadline tracks the first 28°F freeze rather than the first light frost.
How much RV antifreeze do I need?
Most travel trailers and motorhomes take about two to three gallons of non-toxic RV antifreeze, and larger rigs more. Bypassing the water heater saves roughly six gallons you would otherwise waste filling the tank. Buy an extra jug; stores sell out once the first freeze warnings hit.
Can I just use my RV furnace instead of winterizing?
Relying on the furnace is risky. A propane run-out, a tripped breaker, or a dead battery during a cold night leaves the plumbing unprotected, and the furnace may not keep the underbelly and bays warm enough anyway. Draining and adding antifreeze is the dependable way to protect the system.
How do I winterize an RV water heater?
Let the tank cool and lose pressure, then drain it and, if fitted, pull the anode rod. Do not add antifreeze to the water heater tank; instead, set the bypass valves so antifreeze skips the tank and fills only the lines. Fresh antifreeze in an unbypassed heater just wastes several gallons.
When is it safe to de-winterize an RV in Camden?
Wait until the last spring freeze has passed, which averages near Mar 30 here. De-winterize by flushing the antifreeze from the lines, sanitizing the fresh tank, and checking for leaks before a trip. Reopening too early risks a surprise late freeze on a charged system.
Do I need to winterize an RV stored indoors?
A reliably heated indoor space that stays above freezing protects the plumbing, so full winterizing may not be needed. But an unheated garage or barn can still drop below freezing on a cold night. If you cannot guarantee the space stays warm, winterize to be safe.
