Seattle · Towables
What qualifies
A towable is the camper you pull behind your own truck or SUV instead of driving. You supply the tow vehicle; the host supplies the living space. That split usually means a lower nightly rate than a motorhome, plus the freedom to unhitch at the campsite and keep your truck for day trips. PickRV covers four common types. Travel trailers are the all-rounder for families. Fifth-wheels are taller, roomier rigs that connect to a pickup bed for stable long-distance towing. Popup and teardrop trailers are light and simple — easy to pull to a state park lake or a weekend festival. The key number is tow weight: each listing lists dry weight so you can match it to your vehicle. Renters pay one transparent 10% service fee at checkout plus tax, with no drip pricing, and cancellation is free for 48 hours.
Timing
Late June through mid-September, the dry season — and for trailers the winter boundary is harder than most cities': Snoqualmie and Stevens passes require chains on RVs over 10,000 pounds, a threshold many truck-and-trailer combinations cross, making November-to-February mountain towing a specialist's game. Inside the season, the calendar is a set of sprints: Cougar Rock's 6-month window at 7 a.m. Pacific (weekend sites gone in two minutes), Kalaloch's staggered releases (6 months, 2 weeks, 4 days), and Seafair week (typically early August) closing I-90 midday with park rates at 2-3x. Book the mountain nights first; the metro's east-side parks hold availability far longer.
Where it works
Every spot below comes from the Seattle arrival guide — fees, length caps, and reservation windows included.
The east-side anchor built for combinations: 100% full hookups, sites to 67 feet — the metro's longest — with 15/30/50-amp, cable, and an indoor pool at about $70. Unhitch here, 9 miles from the city, and the tow vehicle handles Seattle while the trailer never faces the 80-inch overnight rule at all.
The utility champion at the I-90 mountain gateway: full hookups to 45 feet at $75, a $10 dump, and drive-through propane bays sized for fifth-wheels — the guide's best one-stop east of I-405. Stage here the night before a Rainier or pass-crossing leg and every tank starts the mountain day full or empty as required.
The Olympic coast prize with the catch that defines Seattle trailer planning: most sites cap at 21 feet of RV length. A compact travel trailer or teardrop books ocean-bluff camping at $30 that no full-size rig can touch — via staggered releases at 6 months, 2 weeks, and 4 days for the mid-May-to-late-September season. Arrive with tanks empty; the dump is $10 with limited hours.
The close-in shoreline option: trailers to 40 feet, no hookups, $37 on a 9-month window with a dump and potable water on site. It is the shakedown-night pick — 20 miles from the city, saltwater at the doorstep, and a low-stakes first camp to test the hitch setup before the mountain legs.
What it costs
Towables on PickRV run $65 to $285 per night — below comparable motorhomes, since the tow vehicle is yours. Checkout adds one 10% service fee plus tax; cancellation is free for 48 hours. Site fees span $26-89, ferries charge by combined length over 22 feet, and the compact-trailer premium pays for itself the day Kalaloch's 21-foot sites release.
Good to know
Smaller than you think, if the coast matters: Kalaloch's sites mostly cap at 21 feet of RV length, Cougar Rock at Rainier caps at 35, while the metro parks run 40-67 feet. A compact trailer books everything; a big fifth-wheel books only the metro and pays oversize ferry brackets doing it. Decide the itinerary, then the rig.
Only in the industrial zones — SMC 11.72.070 bans vehicles over 80 inches wide from all other streets between midnight and 6 a.m., and the 72-hour blockface rule (SMC 11.72.440) applies everywhere with Lincoln Towing chalking tires under city contract. Unhitch at the campground instead; recovery from impound runs $400-650.
Both, predictably: WSDOT ferries classify any combination 22 feet and over as oversize with length-bracket fares (and an advance form if height or weight limits are exceeded), while Snoqualmie and Stevens passes require chains on rigs over 10,000 pounds in winter. Summer towing dodges the chains entirely — one more argument for the dry-season window.
