Scotts single ply is not or was branded for RV use
Angle Soft is good too but I do not like the company (no discussion on that or if you try I will ignore you).
That said. I've seen breakdown tests on many brands.. Turns out by the time I take care of the paperwork (No job is done till you finish the paperwork) get re-situated. (Dressed) go out and pull the handle.. IT's had time to break up. More than enough Even Quilted Charman (The worst)
So What do I use? Prince and Spring. the BOXED dot Com House brand.
