I have a 2012 Southwind since 11/11 and have installed 30 amp service next to my house where I store my RV when not on the road. I usually keep it connected primarily to run the AC since South Florida is so hot and humid. I keep it at 80 degrees and so far it seems to be doing fine. We are usually on the road a week a month except during our yearly two month trip. Since keeping it plugged most of the time is almost like full timing it, I don't' see a problem unless maybe the batteries would overcharge/use up water..but was wondering if anyone has any thoughts/concerns. I've not called Fleetwood yet to get their recommendation.
