All you do it your selfers might like this.

This video shows how to make your cabinets out of foam panels and to strengthen them so they will become composite panels.

The second video shows how you can put a outside layer on for the esthetic value or the looks.
Do note that were there are hinges, a piece of wood is installed in the foam panel.


He uses paper bags for his out side look with stain and clear urethane but it may work
equally well with your favorite wall paper.

Enjoy

Be aware that when polystyrene burns, it has cyanide as one of the byproducts.

That is absolutely NOT true. You are confusing polystyrene with polyurethane!

Burning polyurethane can release hydrogen cynaide.

Gene,

The cabinets are attached to the coach by using 1/4 X 20 bolts and a 1/4 X 20 nut plate. The cabinet typically use 4 fasteners and I used some 1/4 X 20 all thread and wing nuts on the bolts on the back. It makes it so much easier to mount the cabinets on the all tread and then put the upper bolts and then put the wing nuts on last.

This picture show the location of the fasteners holding up the cabinet. Notice the wing nuts on the back of the cabinet

The album that your looking at also has many pictures of the 77 coach that I rebuilt. it won second place best coach at the 2002 GMCMI convention in Nashville.

I know this about the cabinets but I see the wood strips you used to hide
the ceiling panel edges. I was thinking of doing this but thought it would
not look so good but I like the way you did it I do use a lot of those kind
of fasteners on other things and it look great now I know how I am going to
do it

Looking online, it looks like it produces styrene gas, which isn't exactly great for you...

However, I didn't see it mentioned in the video, but one benefit of using foam insulation board would be that it has a fire resistance specification built in as it's rated to be used in homes... The Dow Corning stuff sites conforming to ASTM E119 -Fire Resistance Rated Wall Assemblies.

Here's a vid of some guy trying to set fire to one of these cabinets... Based on the fire rating and this video, I would not sweat having these in my coach...

https://youtu.be/cB3PiPaPO_I?t=274

I like the ease and cost of the paper bag method, but it doesn't really meet up with our tastes so far as appearance... But I like the idea of using veneers and even laminates... I was looking at some of the marine foam-core products too, but man, are they expensive... Especially the finish grade panels.

This guy shows a project using walnut veneer that could be applied to RV cabinets. (I would go with the insulation board though, instead of the craft store stuff due to the fire resistance):

https://www.youtube.com/watch?v=-_Lwd4l1Rpo

Formica and some others are even offering metal laminates that would probably work well. Would be useful if you were going for a modern airstream interior look... (Would add to the fire resistance too)

I like the idea of light weight cabinets. Everytime I consider making something for the coach, I think about adding that weight and I put it off.

The paper bag look is supposed to have a leather like look to it. Kind of like that leather that is stitched with small pieces of leather to make a big piece.
I have to say in the right coach, it would look good.

I was wondering, if you used the screen for strength, and flatten it well, perhaps you can use something like wallpaper.
I had thought about using H/D aluminum foil instead of screen, and using a pin to make small holes about 4 inches apart so the glue can dry. Then apply wall paper
onto the aluminum. you would have to level any high edges but if the result was good, you would have a very light cabinet with tasteful good looking side panels.

I am considering adding a table cabinet and thought this method might work if I can make it easy enough to produce it. looking at embedding some wood strips for strength where the table sits/supports from, but not that big a deal.

Its that or buying some composite shelves and cutting them for the cabinet and assembling...

I think it also considers how energetic you want to be on the project, Laughing

I would consider any materials used in GMC cabinets for their resistance to
moisture, mold, and mildew. The fire resistance is important, but that can
be handled with good prevention methods. But these coaches always leak, and
sweat, and set closed up and unused for long stretches of time. Particle
board and composites are not your friend here. Just saying. Spend a bit
more up front on the correct materials, do it once and do it right. The
next owner of your coach will thank you.

I watched the video and liked the idea but the cabinets I need to build run
the full length of the mh along the top. Our plan is to store all the stuff
we carry so my issue is how strong and will they hold the weight
