Just off the phone with my wife, who is at the lake. It's currently blue sky and 84 degrees. Yesterday it was 104. Although at the coast, where I am currently, it doesn't look good.
Havasu is a great place to escape to - but you certainly would not want to live there! Your 40 footer would be pushing the envelope. Probably better to move to Newport Beach and play in the big lake - but to duplicate what you have in VA you would need to add a zero to that number
