What winterizing actually involves
Winterizing an RV around here is about getting water out of the lines before it freezes and splits something. The shops blow out the lines and add antifreeze, but they'll also check the water heater bypass and the outside shower. If you've got a roof leak, that's a separate problem, but winter is when you notice it. Sumner RV Center handles roof work, and Sumner RV Service Center lists roof among its services too. Ask them to look at the sealant while they're up there. It's cheaper than a new ceiling.
Picking a shop
Sumner RV Center has a 4.5 rating from nearly 500 reviews, so they're used to volume. They also do body, chassis, and tires, so you can get more done in one trip. Sumner RV Service Center is smaller and certified, with a 4.3 rating. Both do fridges and awnings. Neither is a mobile tech, so you'll need to bring the rig in. If you're stuck, call ahead and ask if they can fit you in. In my experience, the smaller shop might have more flexibility, but the bigger one has parts on hand.
Book early and ask about parts
The first cold snap in Sumner sends everyone scrambling, so book your winterization before the leaves are off the trees. Ask if the antifreeze and any parts you need are in stock. If they have to order a water heater bypass kit, that's a delay. Also, ask if they'll do a quick check of the roof and awning fabric while the rig is there. Small leaks turn into big problems over the winter. Both shops list winterize, so you've got options, but don't wait until the last minute.
