Winter Rig · Cold-weather RV guides

Winter gear for your rig, researched for real cold

Six guides for motorhomes, trailers, and fifth wheels facing real winter — researched, plain-language, and honest about what is tested and what isn't.

Winter Rig is a small site about cold-weather RV gear, run by Paul, a motorhome owner in Roy, Utah. Paul owns a Four Winds motorhome and put its cover on for winter on October 25, 2026. That cover date is the one personal fact behind this site. The guides themselves are researched — built from manufacturer guidance and published owner experience — not personal test reports, and no procedure here is presented as Paul's personally tested method.

If you only do three things before winter:

Winterize the water system properly — drain, bypass the water heater, and pump antifreeze until every outlet runs pink. This is the job that prevents the expensive damage. Full checklist →
Look after the batteries — a fully charged battery resists freezing; a discharged one can freeze and die. Battery guide →
Cover the rig and check on it monthly — a secured, breathable cover plus a ten-minute monthly check catches problems while they're small. Cover guide →

Affiliate disclosure: Some links on this site are affiliate links. If you buy through one, the retailer pays us a small commission at no extra cost to you — you pay the same price either way. We never handle a product, an order, or your payment; you buy directly from the retailer. We only recommend gear we believe fits the job, and a commission never changes what we say about a product.

How to read this site — honestly

Research — every guide on this site carries this label. It means the guide was built from manufacturer specs, manuals, and published owner experience. We have not hands-on tested every product on these pages, and we say so on the page. Research posts never pretend to be hands-on tests.
Where a number is a typical range — for example, gallons of antifreeze for a motorhome — it is labeled as typical. Your rig's owner's manual wins over any number here, because models differ.
Where a product slot says "to be confirmed," it means exactly that: no model is named until its current specs and listing have been checked. We don't fill product recommendations from memory.

The guides

Motorhome winterizing checklist — step by step before the first freeze
Research The complete job in order: supplies, draining, water-heater bypass, antifreeze quantities, blowout pressure limits, batteries, tires, cover, and winter check-ins — plus a quick-reference table and FAQ.
Best 30-amp RV surge protector, compared
Research Surge-only vs. full electrical management systems: joule ratings, voltage cutoffs, fault codes, portable vs. hardwired, and what each feature is actually worth at a winter pedestal.
Best portable power station for cold-weather RV use
Research Real overnight loads (furnace fan maths included), LiFePO4 vs. other chemistries, cold charging limits, capacity classes, and what a station can actually run — and what it can't.
RV cover buying guide: what fits your rig
Research Measuring any rig — Class A, Class B, Class C, travel trailer, or fifth wheel — typical size bands by type, material trade-offs (polypropylene vs. polyester vs. premium fabrics), breathability vs. waterproofing, and how to keep a cover secure through winter storms.
What to do with RV batteries over winter
Research Flooded vs. AGM vs. lithium storage rules, why a discharged battery is the one that freezes, maintainer vs. trickle charger, self-discharge rates, and a monthly check schedule.
Cold-weather RV mistakes first-time owners make
Research Twelve common, expensive mistakes with their real consequences and the fix for each — plus a quick self-audit you can run in ten minutes.

About this site

Winter Rig is a small, independent site about cold-weather RV gear. It is run by Paul, a motorhome owner in Roy, Utah — not a review company, not a retailer. Paul is learning the cold-weather RV life as he goes, which is why these guides are researched rather than presented as expert test reports — and why corrections from people who have actually done the job are welcome.

Questions or corrections? They are welcome — a correction from someone who has done the job beats a guess from us every time.
