This is something that really depends on your personal preferences and what you are planning for your trip. It is perfectly possible to complete even the longest road trip in just a car. The key to making the car as comfortable as possible is to not overcrowd it with people or things. You should also plan to make more stops to allow everyone to stretch their legs and avoid tight muscles. If you are traveling in a car, staying in motels and hotels can make it more comfortable overnight. However, if you want to have more room and home comforts with you on the road, hiring or purchasing a camper can give you all the space and comfort you need. It also provides you with a place to sleep no matter where you are. A camper can be a great option if there are four or more people on the trip, particularly tall people on the trip, or very young children. Having a space to comfortably and hygienically change your little one can take a lot of the stress out of your road trip. This can also reduce the overall cost of your trip by negating the need to pay for overnight accommodations and restaurant meals.
