Right! When we started looking, we were looking at small popup campers. Hahaha! Just to do short weekend camping trips. Then we kept looking at bigger and bigger. Finally settling in to the one we have. The size of our rig and having 3 dogs limits our choices of place to stay a little bit, but that's OK for us. If you are hoping to stay in National and state parks you find that most are not big rig friendly. So, that will limit your RV choices.
We've met a lot of people who still have a house somewhere and head someplace warm for the winter. That makes sense to do it in an RV.
We had carpeting in our rig when we bought it. We could never get it clean. We eventually ripped it out and put in vinyl flooring. It looks like wood and is so much easier to maintain.
