The Best RV Accessories and Camper Upgrades

An RV is a house that shakes at 65 miles an hour, and most of the parts that make it livable didn't come from the factory. You add them. Power that lasts through a hot night without a generator. Water that doesn't taste like the campground's pipes. A camera so you're not guessing where the back bumper is. The upgrades worth buying are the ones you stop thinking about after a week — they just work, every trip, in the rain, in the dark, at a site you've never seen before.

No single accessory fixes off-grid living, and anyone who tells you otherwise is selling something. Power stations run out. Solar takes a full sunny day to refill a big battery, and a 400-watt roof kit won't run air conditioning. Cell boosters amplify what's already there, so a true dead zone stays dead. Surge protectors can't repair a pedestal that's wired wrong — they just refuse to pass the power through. Every product here asks you to adjust your expectations a little.

Money works oddly in this category. The small items often change your trips the most, while the big-ticket ones change what kind of trips you can take at all. A water filter is a minor purchase and improves every glass you drink. Two kilowatt-hours of battery decides whether you can park somewhere with no hookups. Buy the small stuff first, then the expensive thing you'll actually use. We think that the Jackery Explorer 2000 Plus is the best RV power upgrade for most people, and that the Progressive Industries EMS-HW50C is the one to buy if you spend most nights plugged into campground pedestals.

This guide is for anyone outfitting an RV, camper van or travel trailer with the things that didn't come from the dealer — power, water, electrical protection, connectivity and visibility. If you're a first-time owner, start at the small end: a water filter and pedestal protection cost a fraction of a battery bank and prevent the two most common ways a trip goes sideways. If you're already boondocking regularly, the solar and battery picks are where the money changes what you can do.

It isn't a guide to structural or drivetrain work, and it isn't for you if you camp exclusively at full-hookup resorts a weekend or two a year — a filter and a surge protector cover you, and the rest is optional comfort. We also can't cover every accessory that exists. This is what the research surfaced across power, water, connectivity and safety, not a complete map of the aftermarket.

We built the shortlist around five things. Usable power: rated watt-hours, inverter wattage and charge speed measured against the loads people actually run overnight. Installation: whether it's plug-and-play, a wiring job, or something you should hand to a shop, judged against owner accounts rather than the listing copy. Weather resistance: stated IP ratings, outdoor-rated enclosures and vibration specs for anything living on a roof or bumper. Fit: the amperage, voltage and mounting limits that decide whether a product suits a 50-amp Class A or a 30-amp trailer. Support: how reachable the manufacturer is when something goes wrong, since almost everything here touches your electrical system.

If you want to work from campgrounds with weak signal: The weBoost Drive Reach RV II- Cell Phone ($549.99) — The weBoost Drive Reach RV II amplifies 4G LTE and 5G for every major U.S. carrier at once, with an omnidirectional roof antenna, a 25-foot cable and a directional panel antenna inside that you can aim at your desk. weBoost says it extends reach up to three times the distance from the nearest tower and cuts dropped calls by up to 90%. Owner feedback is more measured, and worth taking seriously: a booster amplifies what already exists, so expect one or two bars of improvement rather than signal from nothing, and expect the indoor coverage area to be small — a few feet around the inside antenna, not the whole rig. People who mount the outside antenna high and place the inside one thoughtfully report it turning an unusable hotspot into a working one. People in true dead zones report nothing at all. A KOA camping report found 65% of RV campers now weigh cell service when choosing a site, up from 48% a few years earlier, so this category matters more than it used to.

If you want to see behind a long trailer: The Haloview MC7109 7'' 720P HD Digital Wireless ($299.99) — The Haloview MC7109 pairs a 7-inch monitor with a wireless 720p camera rated to IP69K — the toughest waterproof rating on the scale — with a 5.9G vibration rating and night vision. The wireless line-of-sight range runs up to 984 feet, which covers a fifth-wheel and tow vehicle with room to spare, and the monitor takes up to four cameras if you later add side or rear-marker views. A bracket adapter is included for RVs prewired for a factory camera, and owners with those mounts describe genuinely plug-and-play installs. The compromises are real but small: it's 720p rather than 1080p, the monitor's interface looks dated next to a phone screen, and a few owners had to add an antenna extender to stop intermittent dropouts. Most say the picture is sharp enough to read a license plate behind the trailer, which is the only resolution test that matters here.

These are the other products the research turned up, not a survey of everything sold for RVs. A product landing here didn't necessarily fail; in some cases it's simply narrower than our picks, or it asks more of you than the alternatives do.

The Garmin RV 1095 ($828.59) — The Garmin RV 1095 is a 10-inch navigator built around custom routing for your rig's height, weight and length, with road warnings for steep grades, sharp curves and weight limits, plus a preloaded directory of RV parks pulling in Tripadvisor ratings, Ultimate Public Campgrounds, KOA and national park listings. Satellite imagery helps at arrival, when you're trying to figure out which way a site actually faces. It's a genuinely useful device, and phone navigation still routes big rigs under low bridges. But owner feedback is more mixed than the rest of this list: the suction mount doesn't hold on textured dash surfaces, the interface takes real time to learn, initial map updates can run for hours, and some owners report occasional detours that add miles for no clear reason. If you drive a 40-foot Class A and want a dedicated screen that knows your dimensions, it's still the obvious choice — just plan on a solid mounting spot and a shakedown trip before you trust it completely.

Two rules save most of the headaches here. First, everything that goes through the roof or the exterior wall needs proper sealant and a yearly look, because a solar mount or an antenna cable entry is a new hole in a structure that flexes constantly. Self-leveling lap sealant on the seam, checked each spring, is cheap insurance against a leak you'll find much later. Second, anything touching the electrical panel deserves a licensed hand if you're unsure. A hardwired EMS has to sit after the transfer switch and before the distribution panel, and getting that order wrong means the unit protects nothing. Buy the wire and connectors before you start, not halfway through. And label what you install — future you, lying on your back in a basement bay with a flashlight, will be grateful.

For this guide:

• We read manufacturer specification sheets for every product here, comparing rated capacity, output, waterproofing and voltage limits against the claims in each listing.
• We reviewed published industry research from the RV Industry Association, KOA, OutdoorGearLab and RVtravel.com to understand how RVers are actually powering and connecting their rigs.
• We read through owner feedback for each product, looking for the complaints that repeat across many buyers rather than one-off failures.
• We read owner reviews on every listing, weighted toward the critical ones, because that is where the recurring failures show up.
• We have a systematic way of automatically fetching the latest prices, so the numbers on this page stay current.
• This is a research-focused guide, so the team may not own every product listed — though we often do own the top winners, which gives us extra context for the recommendations.
• We don't accept free products, and the retailer commission never changes which product we recommend.
