You can Boondock in an RV for as long as you're allowed to in one location and for as long as you're comfortable.
For example some places have restrictions that say you can Boondock in one location or camp in one location for up to 14 days and then you must move for awhile then come back later.
There's no actual limit to how long you yourself can boondock in your RV as long as you're moving on to a new location every 14 days or when the limit is up at your current location.
Dry camping is when you camp without any utilities such as water, electricity etc.
Dry Camping is also known as Boondocking.
In camping Boondocking means that you're camping without any utilities, such as water, electricity, cable TV etc.
However some people who Boondock still have Satellite TV with a portable RV Satellite Dish and use a generator or solar panels to get electricity.
Dry camping is another word for Boondocking as boondocking is any time you camp in your RV without water, sewer, or electrical connections.
This can take the form of parking your rig deep in the back country or pulling over at a highway rest stop.
Stealth Camping is when you camp somewhere without being noticed.
For example you could stealth camp in a van that shows no signs that it is a camping setup inside the van.
Someone might think you would just be sleeping overnight in the van and not actually camping or you might be parked on the side of a road in town and they may think it's just a van.
Stealth camping is camping without being noticed.
Some people will stealth camp in urban areas, while some stealth campers will also venture into wild locations.
Sometimes the camping is considered legal, while other times it's illegal.
For many, it's done thinking it's easier to get forgiveness than permission.
And stealth camping is illegal in most cities.
It has nothing to do with being stealthy, but just the fact that you're camping within city limits, or sleeping in a vehicle overnight.
Stealth camping is sleeping in your vehicle without drawing attention to yourself.
This is similar to boondocking which generally refers to sleeping overnight on BLM or free public lands.
