Maybe this is not really the question you meant to ask as the answer is really quite simple.
I'm kind of wondering if there is a direct correlation between the value of a person's rig and the cost of living. I'm wondering if it could be something as simple as 35%.
NO
So those whose rig is worth $300,000 might have about a 105,000 lifestyle where as it might cost $210k per year to live for those who are living in a $600,000 rig.
NO
If your unit is worth $100 k can you live on $35 k?
YES, but this has nothing to do with the cost of the RV $100k or $300k.
I think it is of some value to have an idea otherwise I might think I can afford say a 500,000 unit and after purchasing it come to realize I can't really afford the $165000 per year it cost to live the lifestyle that goes with it.
Did you really mean you expect to have to spend $165,000/year to live in your RV? NO. $452/day would not be normal. You would really need to work really hard at it!
What are your thoughts?
NO, the cost of living is not based upon the cost of the RV but rather the personal wants and desires of the person making the purchase. Some folks might want to buy an expensive RV so they could show off their wealth to everyone including every stranger in every RV park. If that's you then you are also going to need to stay in the best RV parks to maintain your perception of status. The problem with this is that when you pull into that best of the best RV park you will find a whole lot of folks with a whole lot more RV and a whole lot more money than you which will quickly force you to figure out your place and find that happy medium that works for you.
