The big difference between the RV and the house is the RV is definitely a depreciating asset. Your house may not increase in value but most of the time it does. But it definitely does not depreciate like an RV does. If you put $100K into an RV and $100K into a house, you will have more money still left in the house at the end of 10 years. And the house will give you a place to live once you get off the road.
I am not trying to tell you not to RV full time. I think it is a great idea and the opportunity of a lifetime. Just be sure you have the money you will need once you stop RVing full time.
