most cycle magazines offer trips and trip reports. Yes they are based on motorcycles but they go way more than most rv folks as far as reporting the sights. Rider is a good example, take a look and then go from there. I go to Camp World and get their free rv mags that are offered here in west. I also get trailer life and now buy motorhome they sometimes have duplicate articles but they will get ya pointed in the right direction.
Do a search on the web for 'travel articles' and have some variation there are tons of these things floating around so really you dont need to get a real magazine. here is one that I have as a link: http://www.rvlife.com/
