What kind of camper for trip around the United states

thanks for all the great advise!! So much to research.. right now we are planning to look at a 2005 palomino pop up..and a Keystone FreedomLite 185QB 2008 to kind of get a feel for both.. i am almost thinking the travel trailer LITE might be easier for on the road camping...then setting up and taking down all the time.. the mildew post really got me thinking..especially living in florida, we have to think about that alot! thank you!
