Welcome aboard! You will find plenty of current hybrid/expandable owners here as well as many of us who were prior owners. We had a 2008 Shamrock 21SS bought in 2007 and camped in till 2014!
We kept our 21SS home year-round, parked on a concrete driveway along side our home. Covered only through the NJ winter with an ADCO AquaShed cover. Our new camper is too long to winter at the house so we are storing it for the winter at a public storage facility 10 minutes from our house. The facility actually has 2.5 acres of gravel RV/TT parking that's well-lit, fenced, and closed circuit TV monitoring. Cover it with an ADCO there too.
