We tent camped comfortably for years with an ice chest, five gallons of water, DCell battery AM/FM radio, provisions in the back of the pickup and two flash lights. Never had an issue.
Now with a 25 foot International... Spending hundreds to thousands of dollars in taxes, plates, insurance and maintenance, so we can listen to the radio and have several LED lights over a table at night.
The tent and sleeping bags are rolled up in the closet. Cost is zero to store. Trailer camping may be a bit too rough for us.
