There probably aren't many towns (cities) that have actually changed for the better to those of us who may be over the age of 60. I've lived in Minneapolis, San Diego, Washington, DC, and Memphis (Germantown). I'll take my old hometown of back in the early 60's of Rice Lake, Wisconsin any day. If they could just do something about their snow.....
On to a more serious note. Think very, very carefully about buying a non-venting dryer. Keep in mind that that moisture has only two places it can go. The first is vented to the exterior of your RV and the second is vented to the interior of your RV.
Installing an exterior vent can be a very simple procedure, probably many videos on youtube or the like. I simply wouldn't suggest venting in an RV.
