Our startup costs for full timing

It just occurred to me I should let you all know I'm not trying to be a "Debbie Downer." It's just that I've read many posts over the years of how people are living the fulltime lifestyle on very little money, & having lots of fun doing it. I think it's kinder let people know the lifestyle is not cheap. Our bubble sure got burst when we thought we'd have a great cheap retirement living in a 5th wheel. There are many high costs attached to this lifestyle. Trucks & rv's all need maintenance, Health insurance is very costly which also needs to be considered. Insuring the vehicles for fulltiming isn't cheap either. It's great if someone has a large amount of money set aside to handle the surprise expenses, but personally I don't think anyone is having an exciting retirement on less than $2,000 a month. The numbers don't add up.....sorry.
