Well I finally got around to showing these...been spending too much time camping, playing bluegrass, riding my horses, and enjoying my first full year of retirement...
Now I know many of you have solved the toilet paper holder problem, and frankly my solution was suggested by other posters. I did want to mount the holder and the towel rack, and have them look reasonably attractive and factory. I am posting these for any new buyers or anyone who hasn't figured these out yet.
I was wandering through Home Depot trying to come up with a material to mount these items, wood or whatever, when I spied the PVC siding section. I bought an 8' length of white PVC trim material. Cost was about $13 Cdn. I guess it would be used around windows and doors to finish off an edge. It's about 3/4" x 4 ". It cut very easily with my radial arm saw. I predrilled the holes and then took my angle grinder to shorten the screws so they wouldn't protrude through the back. I fastened them with the 3M black two sided tape used to attach outdoor mailboxes to wood or brick..
I also took a couple of pieces of wood, a 2 x 4 and a 1 x 4 would be perfect, and carpeted them all around so the grandkids would stop slamming the bathroom door into the tub surround. Works perfect.
The final thing is the ottomans we found at Walmart. They fold and two can be easily stored under the dinette while travelling. When put together the can provide some additional storage for magazines, coloring books, video games etc.
For some reason I am unable to post pics of the ottomans. Net must be too slow this aft.
