Thanks for your advice guys,
I know my budget is limited and that it is not really easy to find me someone who will give his mobilhome with me. That is why I posted my request on this forum, hoping that I find a photographer (with a vehicle he hardly uses in automn) who sympathises my project. I can give some money in exchange for using a R.V. (or van), but it won't be as much as commercial carcomponies ask. I don't seek luxury, but I seak a vehicle that is able to drive me across the country.
If I don't find a R.V. (or van), I'll have to look for another way to travel around the country. It's not for the luxury I want a R.V, I think it's the best way to make a photo reportage. I want to see a large part of america, because I want to get to know the country, so I don't want to limit myself to three states (wich would be much easer). The thing is: with a bus or a train, you only get to see cities, and I'm mostly interested in the village life and the America wich you don't see in the movies or on the television.
I want to make a reportage of people who work two shifts a day and of people with two swimming pools. Of a teenage boy whose mind is on baseball the whole day long and of a elderly guy whose mind is on alcohol the whole day (and night) long. And I prefer to go on photographing this guy untill he goes home at 1AM without thinking about a place to sleep that night. Do you get what I mean?
