wants an RV

My husband always wanted to own an RV even though we can not afford one. He said that if we won the lottery then we will have enough money. He is always looking online dreaming of the day he has enough money to buy one. He wants us to travel around the country in it. Every time we passed by an rv parks he has to look and wish we had one. Every time he goes online hoping he can find one that we can afford.
