Motor home hire with living area A/C

Hi all...
So this year was out first ever motorhome holiday as a family, it was amazing fun and we loved it. Don't h think we are ready to make the plunge to buy one just yet but I can't say I am not looking!
We are again looking for next year, but there was one issue that I am sure there is a solution.... it was hot, and I mean hot. With no A/C in the living area nights were not the greatest. (We went to France)
Does anyone know of any hire firms that offer vans with A/C in the living area?
We hired this year from Swift Go, but they don't offer this.
And suggestions are welcome.

Thanks
