Mounting on galley wall (keep us from making a mistake!)

[No More Snow]

I want to mount two fold-up dish drainers from Ikea on either the wall above the sink, or the bottom of the cabinets over the sink, in our 2013 Access Premier 31RP.

I've guessed that the wiring for the two galley lights is in the space between the cabinet bottom and the bottom shelf. But we don't know what else might be in there, or what might be behind the wall separating the galley and the shower. The DH is afraid we might hit plumbing.

The space right at the top of that wall, where the cabinet bottoms meet the wall, sounds solid, but below it is hollow. For all I know there's only 1/4" thick panelling there, which wouldn't hold a hollow wall anchor.

The drainers are solid steel and weigh 4-5 lbs; too heavy for Command hooks, when it's loaded with dishes or pans.

Has anyone done any kitchen mods using that wall, or are there any Winnebago techs out there who can advise us?

If you can mount your dish drainer under an upper cabinet the floor to that cabinet is just stapled in or may be just using gravity to hold in place. Just remove cabinet floor and you will gain access to the backside of the cabinet bottom. Then you can use bolts and nuts with fender washers to attach your drainer. If you wish to mount to the wall, I would suggest molly rivits. Get the 1/4 inch with a 3/16 grip.

My experience tells me that it would be a false bottom as described and the thin panel will not hold weight well. Very slim chance you would encounter plumbing but the wires could be laying anywhere. For safety's sake, remove bottom and make sure wires are routed where they won't be cut with a drill. Locate our screw locations on the very bottom, re-install false bottom and drill up through both. Then use nuts and washers as described, on the false floor. (Like a microwave, radio or coffee maker would be installed)
A molly is typically a metal cylinder that expands. A toggle is typically a spring loaded wing that flips out after pushing though the wall and then acts as a big washer behind the panel. Toggles are more reliable and stronger.
Both require some depth behind the panel and an open area to expand in. If there is no window behind the sink, it is more likely to have something hidden behind the wall than in the cabinet bottom. Odds are, the wall panel is too thin for a screw to hold that much weight and unlikely there is backing for screws in the exact location you want it.

we've attached a number of things using industrial velcro that we bought at home depot. and if that's failed (like it did with the magnetic knife holder in the kitchen) we used goop + industrial velcro (makes the sticky "super sticky")
