First things first, get a good first aid kit ... seriously.

If your camper weighs over 5000 lbs, you are required to have a weight distribution hitch. Don't mess around with your safety, trailer sway is not something to be taken lightly. Consult with your dealer or manufacturer to see what size hitch you need.

These will alert you of pressure loss in your trailer tires and help prevent a blowout. You really don't want a blowout.

This is a sweet generator that you can start remotely from the comfort of your camper on those cold and rainy mornings.

If your power need are lower, this is a nice, light weight generator, It's not quite as quiet as the Honda's but it is close and much cheaper. Also comes with a 3 year warranty.

This surge protector will protect your RV/camper from surges and bad electric feeds when plugged in at campsites.

This adapter will allow you to connect to a regular (household) 110v outlet.

This adapter allows you to plug your 30 amp rv to 50 amp service at campgrounds. You won't always need it, but you may find that the campsite you have chosen only has 50 amp. There is also one for 50 amp rv's to connect to 30 amp service. Find out what you need before purchasing.

Leveling blocks ... yes you need them. You don't want to find out how uncomfortable it is to sleep on an angle.

Small pieces of 2x6 lumber also work well if you have them lying around.

Level your camper, your fridge will thank you with cold food and you'll sleep much better.

Your camper, rolling away on it's own ... not fun.

Another good option for wheel chocks. PROTIP: Put your wheel chocks in place then put your towing vehicle in neutral to let it settle with the trailer, it will make it much easier to unhook.

Get a good cordless drill with a few batteries and a carry case for your stabilizer jacks and general repairs.

Attaches to your electric drill to raise and lower your stabilizer jacks.

Because emptying your black tank is nasty.

Dump hose (be prepared to get a new hose every year or 2.)

This locks down your sewer hose when dumping so you don't get a face full of nasty. Many people use rocks or bricks to support the line but I prefer something that's made for the job, your choice. PROTIP: Once you have hooked up your hose, run your grey water for a few seconds first to make sure there isn't a blockage at the dump station, then run your black, tank flush and grey last to clean your pipe.

Nasty I know, but you're going to know when you're done flushing your tank.

Keeps critters from seting up home in your camper.

This won't stop a dedicated thief but it will dissuade the casual passerby from hooking up to your camper and taking off.

Funnel to add water to your camper through the gravity fill.

White hose rated for potable water.

Hose for non-potable water.

Hose for black tank flush ... never use this for anything else!

High water pressure at campsites can do serious damage to you camper's pluming system. This little gadget will ensure that the pressure is always

A 90 degree water elbow will prevent strain on your city water inlet.

Large capacity RV water filter ... because water at some campsites is pretty nasty!

Here's another good water filtration option.

Things will break on your camper at the least opportune time, be prepared to hadel plumbing issues with a Pex crimping tool.

Things will break, you will need to fix them. Make sure you have the tools you need on hand before you leave.

Get lots of fuses, you'll need them. Note that some campers may also use inline fuses (the glass tube ones) in some areas so you would want those as well. My camper has one for the slide and is behind where the battery sits so make sure you know what you need before you go.

I wasn't initially going to add these but if you have steel steps without any traction stickers they can get pretty slippery when it rains ... ask me how I know.

Here's another step cover option.

Get a doormat ... makes it a hole lot easier to keep the inside of your rv clean.

You're going to want a number of bins in different sizes to keep things organized and ease packing and unpacking. I prefer clear ones so I know what's in them at a glance but that's just personal preference.

A lot of people find stock RV mattresses uncomfortable and replace them right away. Most RV mattresses are not the same length as home mattresses so make sure you know if you have an "RV Queen" size before you buy. Alternatively, many people find that an inexpensive 2" foam mattress topper is all they need and can be cut to size if necessary.

This is a really simple and small cloths line that can be hung almost anywhere. Great for letting the suits dry after a day at the beach.

As the nights get cooler and you start running your heater, you will start developing condensation inside. This can lead to mold and other bad things so try to keep the moisture out.

Refills.

I always replace my shower head to one with an on/off switch right away to conserve water. This would be less of a concern if you plan to spend most of your time at campgrounds with full hookups.

Scott Rapid-Dissolving Toilet Paper is specially made for use in RVs, boats, buses and similar applications.

This inexpensive item will keep you toothbrushes from ending up on the floor during travel.

I use this with either the regular sweeper pads or the wetjet ones. The top half of the handle detaches so it's easy to store.

Of course, you will need cleaning supplies as well.

I use this for laundry but it would make a good place to store toys or other things outside after you've unpacked.

Yo will need a step stool, find one that folds up and can be easily stored.

I LOVE this thing! I have the bigger one at home and keep the mini in the camper.

I need coffee in the morning. This works well on the stovetop if I'm off grid and don't want to/It's too early yo turn on my generator.

Don't forget a good grill set!

Make sure to get one that fits your sink.

If you don't like eating off of plastic plates (me), you need to find a break resistant set of dinnerware.

Another space saver.

You can never have enough kitchen storage. These collapse down and take up very little space when not in use.

Not really an "essential" but definitely handy to keep the bugs away while eating outdoors.

Don't forget to let everyone know where you've been!
