Every time I tow my Globetrotter I find the bathroom base cabinet sliding doors at least partially open and some of their contents on the floor.
I saw a fix for this posted by nyrn where he used rare earth magnets and iron containing screws to keep those doors closed, an elegant modification as most if not all of his are.
I went for something a little simpler for now thanks to an idea GOUSC gave me when I introduced him to 3M VHB tape and 3M Dual Lock, both of which I use frequently to attach (paper towel holder) or hold down (small artificial plants) and many other things in my trailer.
I mentioned to GOUSC nyrn's magnet and screw fix for the doors, and he said "Why don't you try some Dual Lock".
BOOM as the youngsters say these days.
Here is a link to Dual Lock if you don't have any, great stuff to have on hand.

The photos below show how I cut it and after it was installed. Adjust the size of the Dual Lock for the amount of pull you will need to open the door, I ended up cutting 3/8 inch squares. The cabinet door will not close completely but it's a very slight opening, I doubt anyone will notice except you.
