I've went camping before in an RV for a whole month and I was certainly ready to get back to my regular house.
The RV was getting cramped and I love to have space to walk around and have more head room as well.
RV's can be a good fit for some people to live in full time but not for others.
RV's are not that cheap to live in full time either. RVs spaces can cost $500.00 $900.00 per month and then you have your propane tanks to fill and then if you live in a freezing climate you'd could have frozen sewage tanks and lines as well.
And you'll likely have to change out the propane tanks often.
