We (the DW, and ME too ... no stereotyping) drycamp and/or drycamp-boondock all the time in our RV and live the same way we do at home. That's what the big-bucks one pays for an RV is supposed to buy you, IMHO. I wouldn't buy an RV if it didn't make that possible ... otherwise break out the tent and save the expense of the RV.
For instance:
- We keep it's interior temperatures 60-65 degrees on cold nights.
- We take showers every couple of days.
- We microwave fresh vegetables in steamer bags.
- We make healthy green-drinks using our blender from the home kitchen.
- We bake blueberry pies in the oven.
- We heat the RV up to 74 degrees while we shower so we don't step out into a "cold feeling" interior.
- We shampoo the dog out on a picnic table or out on our foldup table and dry her off with the hair dryer on the end of an extension cord - powered by the built-in generator.
- We play board games, watch movies, read books in the evenings under nice bright but non-glaring warm spectrum LED lights.
- We take naps during the afternoons in scorching heat in complete comfort with the A/C doing it's thing.
- We surf the NET out in the middle of nowhere using our long range cellular system.
- We can watch lightening storms cross the desert in the pouring rain with a nice cozzy interior because the vents can be open in the rain under their vent covers.
- We can travel offroad on dirt roads while maintaining a dust-free interior by maintaining air pressure inside the coach.
- On moderate temperature nights, we can maintain a gentle airflow the length of the RV using front-rear vents open with a fan in one of them set to low.
- We can keep the bugs out of the interior by vacuuming them up with either the built-in generator or an inverter to power the RV vacuum for a couple of minutes.
We can do things like those above off the grid for about 6-7 days in only a 24 foot good ground clearance Class C that drives like a van and can go to many of the same places that a truck camper would go to. However, we sometimes have to drive very slow and careful to do it!
