Tent Camped? If so... you are already an Expert!
Have you tent camped?
If so... you are already an expert.
Then it is just a matter of becoming comfortable with towing an apartment with all of the amenities that were lacking in a tent.
If not... I have not found a book on Boondocking. There are few trailer owners who actually Boondock. You need to begin at RV Parks and when comfortable having that under control, expand to campsites in your general area.
Trailer LENGTH is important if you actually camp versus RV Park your trailer. Keep that in mind. The longer your trailer, many options are not accessible.
The National Forest campsites without electricity, city water and pit toilets are your next step.
National Forest hunter camps that are pullouts off a main Forest Service Road is considered Off the Grid camping.
Your comfort level should then allow you to experience Base Camping at a remote site, set up camp and detach the trailer. Your tow vehicle will take you to all of the Boondocking campsites you can manage to get your trailer.
Reading Threads on the Boondocking Forum is the best 'book' from experienced owners.
Experience is 'earned' from numerous Trial and Error experiences with your trailer in tow. Much like learning how to drive, Boondocking is a hands on learning curve. When the Airstream Dealer attaches your trailer to your tow vehicle... you are on your own.
Welcome to the best website for information on the Internet. You are among a great crowd and many could write a book on Boondocking, but why encourage too many more Airstream owners, taking the best campsites!
