RV Essentials Gear Checklist for Beginners (2026)
New RVers tend to overbuy the fun stuff (grills, string lights, camp chairs) and underbuy the boring stuff that prevents disasters. This checklist covers the five unglamorous categories experienced owners say they wish they'd bought on day one: power protection, water protection, leveling, waste handling, and tire monitoring. Real product examples included, claims kept modest.
How we chose
We did not hands-on test these products. We identified the categories from recurring beginner-mistake patterns in full-timer communities, then selected widely-used products from established RV brands (Camco, Progressive Industries, TST) based on published specifications, warranty terms, and long-term owner feedback. These are the defaults of the RV world — popular because they work, not because they're exciting.
1. Surge protector / EMS (electrical management system)
Campground pedestals are notorious for miswired outlets, low voltage, and power surges. A basic surge protector guards against spikes; a full EMS (like the Progressive Industries units) also cuts power on low/high voltage, open ground, and reverse polarity — the faults that quietly kill air conditioners and converters.
Why it matters
- One bad pedestal can fry thousands of dollars of electronics
- Plug-and-play: no installation for portable models
- Full EMS units diagnose the pedestal before you plug in
Watch out
- Buy the right amperage — a 30A protector on a 50A rig leaves you unprotected
- Full EMS units cost several times more than basic surge-only models
Who it's for: Everyone who plugs into shore power. No exceptions — this is item one.
Who should skip the full EMS: Strict boondockers who never use hookups can start with a basic surge protector.
2. Water pressure regulator
RV plumbing is typically rated for 40–60 PSI, and campground spigots can deliver far more — especially at elevation-fed parks. A regulator screws onto the spigot and caps pressure at a safe level. The basic brass models (Camco's is the ubiquitous one) cost little and last years.
Why it matters
- Prevents burst fittings and interior flooding — the classic rookie disaster
- Costs less than a fast-food meal; adjustable models with gauges cost only a bit more
Watch out
- Fixed regulators can slightly reduce flow at low-pressure campgrounds
- It's small and easy to leave behind — make it part of your departure routine
Who it's for: Anyone connecting to city water. If you only ever fill your fresh tank, you don't need one.
3. Leveling blocks
Almost no campsite is level. Stackable interlocking blocks (Camco's yellow leveling blocks are the classic) go under the low-side wheels; drive up, check with a bubble level, add or remove blocks as needed. Your absorption fridge needs reasonable level to run properly on propane, and you'll sleep better too.
Why it matters
- Cheap, light, and you'll use them on most trips
- Protects fridge function and slide-out operation
Watch out
- Don't use stabilizer jacks to lift the rig — they're for steadying, not leveling
- On very soft ground, put a board under the blocks so they don't sink
Who it's for: Every towable and most motorhomes without auto-leveling.
Who should skip: Rigs with hydraulic auto-leveling already installed.
4. Sewer kit
Dumping tanks is part of the deal. A proper kit means a sturdy, supported hose (not the flimsy starter hose many rigs ship with), a clear elbow so you can see when the tank runs clean, and disposable gloves. Camco's RhinoFLEX kits are the widely-recommended upgrade: crush-resistant hose, secure bayonet fittings, and end caps for storage.
Why it matters
- A hose failure at a dump station is the mess you never forget — good hoses prevent it
- Secure fittings stay attached; cheap ones pop off
Watch out
- Kits are bulky — confirm you have bumper or bay storage
- Rinse the hose and your hands thoroughly after every dump; keep a dedicated rinse hose
Who it's for: Anyone with black/gray tanks — i.e., nearly every RVer.
Who should skip: Cassette-toilet van builds that dump at restrooms instead.
5. Tire pressure monitoring system (TPMS)
You can't feel a trailer tire going soft from the driver's seat — and RV tires fail from age and heat long before the tread wears out. A TPMS (TST's 507 system is the long-standing favorite in RV circles) puts sensors on each valve stem and shows real-time pressure and temperature on a dash display, with alarms for leaks and overheating.
Why it matters
- Early warning of slow leaks and overheating — the two main blowout causes
- Especially valuable for trailers, where you can't see or feel the tires
Watch out
- Sensor batteries need periodic replacement
- Long trailers may need a signal repeater for the rearmost sensors
Who it's for: Trailer owners and anyone running long highway days. Strongly recommended.
Who should skip: Honestly, very few — but if your rig already has factory TPMS on all positions including the toad/trailer, you're covered.
The quick-start shopping order
- Surge protector / EMS — before your first hookup, period.
- Water pressure regulator — cheapest item, biggest disaster prevention per dollar.
- Leveling blocks — you'll use them constantly.
- Sewer kit upgrade — before your first dump station visit.
- TPMS — before your first long highway run.
Bottom line
None of this gear is glamorous, and that's the point: the boring stuff is what keeps a first trip from becoming a cautionary tale. Get the five categories above sorted, and you can spend your energy on the fun part — everything else can wait for trip two.

Frequently asked questions
What is the most important piece of gear for a new RVer?
A quality surge protector or EMS (electrical management system). Bad pedestal power at campgrounds is common and can destroy your RV's electrical system in seconds. It's the cheapest insurance in this entire checklist.
Do I really need a water pressure regulator for my RV?
Yes. Campground water pressure can spike well above what RV plumbing is built for — typically rated around 40–60 PSI. A regulator is a low-cost part that prevents burst fittings and flooded floors. It's the highest value-per-dollar item on this list.
How do I level my RV at a campsite?
Drive the low-side wheels up onto stackable leveling blocks, then fine-tune with the rig's stabilizer jacks (stabilizers are for steadying, not lifting). A small bubble level or phone app on the floor tells you when you're close enough — your fridge, in particular, needs to be reasonably level to run properly on propane.
Is a tire pressure monitoring system worth it for an RV?
For trailers especially, yes. You can't feel a trailer tire going soft from the driver's seat, and a blowout at highway speed can cause thousands in body damage. A TPMS gives you real-time pressure and temperature alerts and is one of the most-recommended safety upgrades among experienced owners.
