Forget it. As mentioned a safe grab bar needs something more than double sided tape or adhesives. You would also need to be concerned about the strength of the thin plastic bathroom lining material. Don't worry about screws going into the textured surface, you need to use heavy screws or bolts into structural material behind the surface.
Correct!
From
HERE"A grab bar is only as strong as the anchoring devices and the wall on which it is mounted. Fastening directly into wood “stud” blocking is highly preferred. If wood blocking is not available and you are installing on a hollow wall, be sure to use a hollow wall anchors"It is highly recommended to mount grab bars through the shower/tub wall and into wood studs. In some cases there may not be studs where you need them and in those cases a toggle hollow wall anchor to spread the load across the back of the wall board (typically drywall board).
With the thin walls of RVs even toggle hollow wall anchors most like will not be sufficient.
I seriously doubt that any glue on bars will be safe at all, if you can even find them for sale.
There are suction cup types, but on a textured surface it would be doubtful that would work.
Not to mention, I have learned over the yrs not to trust suction cups for something this important.. Had a nutty manager decide that my team use manual lifting suction devices to lift 100 lb servers out of the boxes.. First try and one of the suction cups let loose and we nearly had a 100 lb $4K server not only hit the ground but also targeting our feet.. Needless to say, I told the manager where to put his suction cups and idea..
Is there any way you can gain access to the back of the shower wall and add in some plywood to provide strength and a place to screw into?
As far as holes in the surround goes, that is what sealants are for..
