So here I am ready to get organized drilled small pilot holes in the back of the basement to mount some fancy spring clips and it appears this is just Styrofoam and nothing for the screw to bit on. Does anyone know if there is any support beams or studs in these compartments ?
First off, I want to thank all of you for the nice comments. As stated, it's kind of a hobby for me now that I'm not doing it for living/overtime assignment.
Fleetwood Couple,
Many of these compartment walls are lined with a foam. There should, be a light duty aluminum backing behind that foam. One of the first things you or, anyone intending on mounting things on either the back wall or side wall of a compartment should do is, try and investigate just what's behind that wall you're getting ready to drill a hole through. Sometimes you need to get under the coach and probe around, do some measuring, anything you can, to make sure that you're not going to drill into a FUEL OR WATER TANK or, anything else of importance.
But, on many of those walls, they are basically light skinned aluminum, steel or possibly plastic or fiberglass walled cabinets with foam in between the skins. So, if and when you drill, do be careful and when attaching a bracket/clamp/tool holder/etc. do not screw down things too tight. You'll crimp the two sandwich walls together or, possibly even pull the screw head or nut right through the light skinned wall.
I've used many body washers on the back side so that will not happen. It spreads the load out for the clamping screw and nut. As to your question of "Studs", well, not that I've found. For much of the mounting of many of those brackets and holders, it was "blind" fastening. What that means to those of you that are not aware of that term is, you cannot get to the back side of the wall with a nut or, backing of any type for the screw (that holds the intended bracket)to attach to.
In that case, I use what's called "nutserts" or also known as "Rivnuts". They are a fastener that acts much like a rivet only, there's machine screw threads left when you remove the mandrel. Then, all you do is put your bracket in place and, screw in a machine screw. That's much stronger than using sheet metal screws.
