Bro, I had the great idea that I could travel cheaper and farther by tent camping.... unfortunately what I learned is that while it can be cheaper if you stay at the right location, it is only a night or two that makes it cheap and what you have to do to make up for what you loose negates your savings.
Example, National Forest lands allow you to camp off road or off trail at "unimproved" areas for free, but if you do this you have to travel to get water and facilities such as a shower or bathroom. Camping inside rec areas with facilities can cost between 15 to 30 dollars depending on where you are and how much "service" you want.
State parks vary greatly, many charge upwards of 15 to 25 dollars to camp now, and sometimes more... your local KOA on the other hand has nice facilities and sometimes a pool for between 22 and 30 a night.
Most areas I travel through and a cheaper motel, for example Dave0430 and I were able on our trip (through NM and back to AR) to find a motel 6 at 29.95 and so the price difference hardly made it worth the sacrifice in comfort of tenting it.
If how ever you are determined to camp it out, remember you can camp on FEDERAL lands FREE if you choose and unimproved site... for example, you can simply use any turn off from the road in a National Forest and set up camp for the night. No fee is needed.
This is why I am saving my money for a tear drop to pull behind my bike... when at a destination per se' I can camp with it and use electricity, water etc and even have heat or air if I want at a reasonable fee... if I am not at a destination and need to get a nights sleep and Walmart nation wide will allow you to park over night on their lot for free so traveling with a tear drop means I can stop at rest areas, Walmarts, malls etc when |I get tired an simply crawl n bed for some zzz's.
Hope this is helpful.
