help. camper full of mildew

We live in Georgia and have had a very wet summer. Our 34ft 5th wheel has been covered since June. We have not had the chance to get out with it all summer and now are going next week on vaca. Imagine our surprise when we uncovered it today, went inside and found every surface covered with mildew. We used a bleach/water combo to clean walls, cabinets. Took out all bedding, jackets, vacumned, washed etc. but am now pretty concerned about the furniture,carpet and the mattress. Can anyone tell me what kind of product can safely be sprayed on carpet,sofa,chairs,valances and even the day night shades got it. I am washing every dish and pan in the dishwasher, any paper products am throwing out. Nothing was left untouched. I would appreciate any help we can get please. Thank you
