If your worried about it...run.
1 you will always loose money
2 you will aways pay piles for repairs
3 your breakdowns will always occur in the middle of no where
4 you will run into small things no matter how careful you are
From a financial stand point the entire RV thing is a huge mountain of money.
That said we are in Valdez Ak on day 55 of our alcan adventure.
Bottom line..... you can always get more money, but you can't get more time.
Look at obits in your local paper at those much younger then that are gone. Sobering.
No reason to be foolish with money but don't let it ruin your dreams.
Imho
