Need that morning coffee? You can get a device that makes a full pot and plugs into the cigarette lighter on your vehicle! Keeping your food cold is important and you can’t always count on being able to get to town to get more ice. A compact refrigerator and even compact freezer can be ideal for your vehicle by the river.
If you plan to be at the river for a period of time, consider building a box like contraption that will be hard for any animal to open. This can be a wonderful way to store the trash until you can take it to another location. It also keeps the trash outside so that significantly reduces the risk of the vehicle starting to smell because of it.
If you plan to create a vehicle that will have running water for the sink, shower, or toilet, you are going to need a water tank. You have quite a few options with them including the size. The more water you need to use daily the larger size you will need to get. They are going to take up several feet of space.
