The first step to ensuring a successful road trip on a budget is planning ahead. Not only should you plan out the rout you will take, look at weather, find camping gear at thrift stores and go grocery shopping beforehand so you’re not eating out.
Camp Sites
Although camp sites usually don’t cost too much, the price of camping at many different locations throughout one trip can add up. Here are some websites to help you find free camping locations along the way!

Groceries
Eating out is usually a huge cost of traveling, but it doesn’t have to be. Plan out what meals and snacks you and your group will want on this trip. Take into consideration; where you are traveling, how many people you are with, will you have access to a refrigerator, and what activities you will be doing.
