Travel Trailer Must-Haves For Your First Trip
A new trailer comes with almost nothing. Here is the short list that is genuinely trip-critical, and the long list that is not.

Quick picks
Scored on how often you will actually use them (40%), build (25%), packability (20%) and price (15%). Everything here gets used on the first trip.
| # | Product | Best for | Score | Price |
|---|---|---|---|---|
| 1 |  Progressive Industries EMS-PT30X Electrical Management System, 30 Amp A full electrical management system, not just a surge protector: it reads the pedestal and disconnects on low or high voltage, which is the fault that actually kills air conditioners. Buy first | Most 30-amp trailers — the one to actually buy | 8.7/ 10 | |
| 2 |  Camco Adjustable RV Water Pressure Regulator, Lead-Free Brass Adjustable lead-free brass with a gauge. Being able to dial pressure down to about 50 psi matters because a campground pedestal can deliver far more than your plumbing is rated for. Do not skip | Setting your own pressure instead of accepting a preset | 8.2/ 10 | |
| 3 |  Camco RhinoFLEX 20 ft Complete RV Sewer Hose Kit The default sewer hose for a reason: a reinforced 23-mil wall that holds its shape, swivel fittings on both ends, and a complete kit so you are not ordering an adapter from the dump station. Essential | A first sewer hose that will not need replacing in a season | 8.0/ 10 | $63.00View on Amazon
|
| 4 |  Camco TastePURE 25 ft RV Drinking Water Hose A drinking-water-safe hose in the length that reaches most pedestals. A garden hose is not a substitute, and this is cheap enough that there is no reason to use one. | The drinking-water hose you should own before anything else | 7.8/ 10 | $13.97View on Amazon
|
| 5 |  Camco RV Wheel Chocks with Rope, 2-Pack Two plastic chocks with a pull rope so you can retrieve them without lying on the ground. Unremarkable, correct, and the first thing to buy. | The basic chock every trailer needs before anything else | 7.9/ 10 | |
| 6 |  Camco FasTen RV Leveling Blocks, 10-Pack Interlocking plastic blocks that lock together instead of sliding apart, which is the whole difference between these and loose wood. They also go under a jack, which a curved leveler cannot. | The default: cheap, interlocking, use them for everything | 7.5/ 10 | |
| 7 |  Milton S-986 Dual Head Tire Pressure Gauge, 10-160 psi Trailer tires often run 50-80 psi, which is past the top of a typical car gauge. This one reads to 160 psi and the dual head reaches an inner dually valve. Cheapest fix on the list | Reading trailer tire pressure that a car gauge cannot | 9.6/ 10 | |
| 8 |  TitanFlex Heavy Duty Nitrile Gloves, 6-mil, 100-Count Six-mil nitrile, fully textured. Thin exam gloves tear on a bayonet fitting; these are the thickness that survives connecting and disconnecting a sewer hose. | The dump station, and not thinking about it afterward | 8.3/ 10 | $14.99View on Amazon
|
| 9 |  Camco Sidewinder Telescoping RV Sewer Hose Support, 20 ft A rigid folding trough that holds the hose in a steady slope. Without one, the hose sags, the sag holds waste, and the smell you blame on the hose is actually the sag. | Giving the hose a continuous downhill run | 6.9/ 10 | |
| 10 |  Camco PowerGrip Dogbone Adapter, 50A Male to 30A Female, 55175 The adapter for a 30-amp trailer at a 50-amp post. Ten-gauge copper and a molded grip, and it does not give you more power — it gives you a connection. | Plugging a 30-amp trailer into a 50-amp pedestal | 8.4/ 10 |

The short answer
Search “travel trailer must-haves” and you get somebody’s entire garage. A hundred items, half of them because they are fun. This page is the shorter, duller list: what you cannot complete a trip without.
The eight you actually need
01An electrical management system (not just a surge protector)
The campground fault that damages equipment is sustained low voltage in a full park, and only an EMS disconnects for it. Buy the amperage that matches your service — three prongs is 30 amp, four is 50. Why EMS, not surge.02A water pressure regulator
Pedestals can exceed 100 psi; RV plumbing is designed for far less. A burst fitting inside a wall is slow to find and water damage writes trailers off. Adjustable with a gauge.03A drinking-water-safe hose
A garden hose is not potable-certified and makes the water taste of hose. Twenty-five feet reaches most spigots. Hose picks.04A 20 ft sewer hose kit
Two 10 ft sections with rotating fittings and a stepped 4-in-1 adapter. Ten feet does not reach on a lot of sites. Sewer hose picks.05A sewer hose support
Not an upsell. Without one the hose sags, the sag holds waste, and the smell you blame on the hose is the sag. Support options.06Four wheel chocks
Four, not two, on a tandem axle. A chock only works in one direction. Chock before you unhitch, every time. How many you need.07Leveling blocks
An absorption fridge needs the trailer close to level to cool properly. Interlocking blocks also go under the jacks, which a curved ramp cannot. Block picks.08A tire gauge that reads above 60 psi
Trailer tires frequently run 50-80 psi and most car gauges top out around 50-60. A gauge that cannot read your pressure is worse than none, because it gives you a number and the number is wrong. The psi guide.
Nitrile gloves make nine, and they count. Six-mil, not thin exam gloves, which tear on a bayonet fitting at the worst possible moment.
Plus one adapter
A 50 A male to 30 A female dogbone, if your trailer is 30 amp. Some sites only have 50 amp pedestals, and without the adapter you cannot connect at all. It is a small, cheap item that occasionally saves the whole evening. Which adapter is which.
What can honestly wait
All of this gets recommended as a must-have and none of it is:
| Item | Why it can wait |
|---|---|
| Outdoor rug | Nice. Not functional. |
| Curved levelers | Blocks do the job; buy a ramp when restacking annoys you |
| Tire pressure monitoring system | Genuinely valuable, and not needed on trip one |
| Water filter | Taste, not safety, on municipal supply |
| Wheel stabilizer (X-chock) | Comfort on a tandem axle, useless on a single |
| Tank treatment | Useful by week two, not on day one |
| Backup camera | Learn to back up first; then decide |
| Surge module spares, extra fittings | After you know what you break |
Two of those deserve a note. A TPMS is one of the most genuinely useful accessories on the whole site — a trailer tire going down is invisible from the driver’s seat until it comes apart — and it is still a second-trip purchase rather than a first-trip one. The TPMS picks.
And a curved leveler is the upgrade most owners end up thanking themselves for, just not before they have discovered why.
The common mistake
And three things to do, not buy
Measure your loaded tongue weight. It sizes your hitch, decides whether you need weight distribution, and tells you how much payload you have left. Three methods, one free.
Torque the trailer lug nuts, and again after the first 50 miles. New trailer wheels loosen and it is more common than it should be.
Practice backing up in an empty parking lot. An hour on a Sunday morning is worth more than any amount of reading, and it is a much better place to learn than a campground with an audience.
Then work through the setup checklist and the first-trip guide.
What to remember
- Eight items are trip-critical: EMS, regulator, water hose, sewer kit, hose support, chocks, blocks, tire gauge.
- Buy the EMS for your actual service — three prongs is 30 amp, four is 50.
- A tire gauge that stops at 50 psi cannot read trailer tire pressures.
- A TPMS is genuinely valuable and still a second-trip purchase.
- Measure tongue weight and torque the lug nuts before the first trip.

Camco Adjustable RV Water Pressure Regulator, Lead-Free Brass

Common questions
An EMS matched to your service, a pressure regulator, a drinking-water hose, a 20 ft sewer kit, a hose support, four chocks, leveling blocks, and a tire gauge that reads above 60 psi. Plus gloves and a 50-to-30 adapter.
Good value and they save eight separate orders, but they consistently include the entry-level version of a couple of things you will upgrade — usually the regulator and the sewer hose.
Not on the first trip. Most campground water is from tested municipal supply, so the problem is taste rather than safety, and a cheap inline carbon filter solves that whenever you add it.
