upholstery question

Hi all! My husband just got home with our "new" 1999 3124 KB. This is our first camper and we are taking it to a local campground this weekend. We want to clean the upholstery on the couches and the bed covers. (The couches have the mauve and green floral print; the bed covers have that velour like material on top and vinyl around sides.) Can these be machine washed on delicate and hung out to dry? We really want to get going on the cleaning this evening....of course we're excited! So any speedy advice would be greatly appreciated.
