Central Washington RV
Yakima RV dealer with a 4.7-star rating and 288 reviews, known for kind staff and no-pressure sales.
Yakima cold comes on fast once October turns, and a burst pipe or split fitting on an RV water system is a miserable way to start a trip. Two shops here handle winterization, and both know the freeze-thaw swing that hits the valley. You can book a shop bay or have a mobile tech come to your storage spot, which beats hauling a rig across town when the lines just need blowing out.

Central Washington RV is the bigger operation, with 288 reviews and a 4.7 rating, and it covers far more than winterizing: roof, A/C, fridge, awning, water heater, slide-out, tires, electrical and generator work. If something else is acting up, you can get it looked at in the same visit. Tonys Mobile RV Service comes to you and handles roof, A/C, fridge, awning, water heater, furnace, slide-out and winterize jobs, plus weekend and emergency calls. Mobile makes sense if your rig is already parked and hooked up, or if you don't want to move it. Shop work makes sense when the tech needs a lift or a part on the shelf. Ask which one fits your job before you book.
A proper job drains the fresh tank, blows the lines, runs RV antifreeze through the taps, toilet and water heater bypass, and checks the low-point drains. Ask whether they pull the water heater plug and whether they treat the black and gray tanks. Yakima's freeze-thaw cycles are hard on exterior fittings and the city water inlet, so have those checked while the tech is there. If your rig has a washer or an ice maker, say so when you book, since those lines take extra time and not every shop stocks the fittings.
The first hard freeze usually catches people mid-project, and the week before it is the worst time to call. Book in early fall if you can, and ask whether the shop keeps antifreeze and fittings in stock so you aren't waiting on a delivery. Warranty pre-approval matters too: one of the two Yakima shops does warranty work, so if your rig is covered, call ahead and let them sort the paperwork before the appointment. Roof and sealant checks fit neatly into the same visit, and Yakima wind and summer sun chew up lap sealant faster than you'd think.
There are 2 winterization options listed in Yakima, with 2 more nearby. One is Central Washington RV, a full shop, and the other is Tonys Mobile RV Service, which comes to your rig. Both list winterize among their services.
The average across the listings is 4.6. Central Washington RV sits at 4.7 from 288 reviews, and Tonys Mobile RV Service is at 4.4 from 32 reviews. Review counts vary a lot between a shop and a mobile tech, so weigh that when you compare.
Tonys Mobile RV Service handles mobile calls, including weekends and emergencies, and lists winterize. Ask about access at your storage lot and whether water and power are available on site. Some spots work fine with a portable tank and a generator; others don't.
One of the two does warranty work. If your rig is still covered, call before booking and ask about pre-approval, since the shop needs the claim sorted before the tech starts. Have your policy or contract number handy when you call.
