We have a walk around bed, but when I had back surgery last spring, DH wanted to be able to make the bed, so we decided to buy the RV superbag. The company that makes the original Travelsak is out of business. The company that makes the RV superbag leaves a lot to be desired and the owner is a real jerk. We ordered and paid almost $400 for a queen set and six week later, we still didn't have our bag. We called back and forth and got little satisfaction. When we finally did get the bags, they were the wrong fabric. They refused to pay the freight for me to send them back. I did end up getting my money back, minus the freight. I mean, they couldn't deliver what I ordered, so they made me pay to have the wrong one returned. We cancelled anyway. A few days later we visited the Camping World in Greenwood, Indiana. They had TWO of the original Travelsak bags on clearance. We bought one for $98 and the next week went back and bought the other, just because it was a good deal and a great price. Now we have a backup.
You can easily make your own sheet sack. I'm going to do just that to have extra sheets. Two queen size flat sheets with sewed on velcro on both sides and the bottom will work. By being able to separate the sheets totally, they will fit in my Splendide. The king sheet I have now is one piece of fabric that folds in half. Too big for my washer.
