I've been using a RV Superbag sheet/comforter system for the past 3+ yrs in both my Sportsmobile and EEXP. My girlfriend and I love it and it has worked pretty good. Love that it feels pretty much like a typical bed setup and that you can unzip both sides for ventilation. I've basically worn it out/put it in the dryer, which your not supposed to do. Need to get a new sleep system for the both of us to use in the FULL size bed in the EEXP. Any suggestions on systems that have worked for you?
