We've found that Velcro (or hook & loop as its generically called) is handy to have in the motorhome. You can buy it in different colors, sizes, and different strengths. We use the narrower widths to tame power cords, hoses, and cables.
We use Velcro to attach our Advantage PressurePro tire monitor system display screen just below the driver's window, to attach our air bed controllers to the wall, to keep a voltage meter handy in the battery compartment, and to hold other items secure.
I've also attached a strip of the soft side to the interior wall of the pantry. Then I attach a small piece of the hook side to small spice jars or other lightweight jars. Putting the small bottles up high keeps them from getting lost amongst the larger items.
I've attached the soft side of the Velcro to the underside of things that slide to make them slide easier. I put the soft side on the underside of the white plastic container in the bottom of the refrigerator. That's where we keep larger items. And I've also attached it to the underside of a large drawer organizer that holds office supplies. The organizer slides into the overhead cabinet and the soft Velcro keeps both of these storage containers from scratching every time we move them.
