The first thing on our camping checklist is a tent with a rain fly. Unless you're going to a camping spot with pre-installed cabins or tents, you'll need a tent or outdoor shelter. A tent protects you from the natural elements and ensures that you have a safe space to sleep once night comes. You never know what might happen when you drive your RV to your campsite, so carry a tire pressure gauge to keep an eye on your tires.
I personally bring several types of fire lighters, including a Bic lighter, fireproof matches and a small flint kit Yes, tents are necessary when you are considering what to bring to the campsite, however, you don't need a new tent every time, as long as the tent that You have it made for the weather conditions you'll face. And if you're going glamping, you won't need a tent but things like a durable outdoor tablecloth will come in handy. If your cabin has outlets, you'll want to carry chargers for your mobile phone, tablet, or laptop (if you bring them and there's WiFi or if you use an access point). What they don't provide are clean sheets, so bring your own sheets, pillows, duvets and blankets. In addition to a first aid kit, you should also carry a tool kit with you during an RV camping trip.
Regardless of where you camp, it's good to have mosquito repellents when you're thinking about what to bring to the campsite. In addition to wearing your favorite pajamas and loungewear to relax inside the vehicle, you should also wear hiking clothing (including good base layers, outer capes and socks), swimwear for any campsite pools or designated swimming areas nearby, and even more elegant clothing for taking pictures while you are doing sightseeing. Soap, toothbrush and toothpaste are essential items you don't want to forget, and I like to use dry shampoo instead of liquid shampoo and conditioner to quickly refresh my hair. However, if you bring the wrong things or simply too many things, this will significantly hinder your night outdoors and you may find yourself without the needs you should have planned.
As a child accompanying my brother's Boy Scout camps, I learned that you should always, always, bring an extra set of clothes and shoes.
