I have been usually using the TP-in-a-plastic bag thing, except when doing a #2, when I use RV TP which I can flush. However, when company comes, I don't ask guests to do that and have gotten into trouble when I have a houseful of grandkids. I hate the stuff Camping World and other RV dealers carry, so have been looking for a solution.
I found Scott's Rapid Dissolve TP way last December and loved it. It dissolves extremely rapidly, is bright white, and ribbed so it feels stronger and thicker than it is. I have been searching for it everywhere since then, with no luck. It is supposed to be carried at Walmart, but have not been able to find it there. Finally gave up and bought a case of 12 packages of 4 double rolls through Amazon for $34 with free shipping when I added another small item. Now I have about two year's worth of this stuff stashed underneath in storage. (Strangely enough my son who gets all my mail did not question why I was buying TP from Amazon! )
