Margaret...we've heard those same stories about TP, too. HOWEVER, take a square of the special stuff and a square of Northern.....put them in separate bowls of water and time them....how long does it take for each to dissolve???? Yeah....Northern dissolves fast. In our opinion, both of us have RVd for more years than we want to count, it isn't how FAST necessarily that TP gunks up the holding tanks...it's how MUCH is used. Many people roll out WAY too much TP.. :) :) Just our opinion. :)
As for your original question: I set aside everything I use at home on the counter starting about a week ahead, then I determine whether I'll REALLY use them on the road. :) The only thing I forgot last time was the wine cork.......which was no problem cuz we bought screw top bottles. :) :) :)
Happy trails!
