Based on what others have posted about condensation issues in cold weather because these campers have no insulating feature for the top bed, I chose to do something a little different for cab overhang bed board.

From my salvage camper, I cut out a section that would be on the bottom and exposed, because it was only 3/8 thick with an aluminum skin that was glued to it, thus very weather/ water resistant, and I used butyl tape to seal it the channel perimeter.

Then a middle section for 1/2 inch foam insulation R-3

On top was 3/4 inch pre finished Birch plywood, which is the primary support for the whole bed arrangement.

I know I'm giving up a little space in the bed area for mattress thickness, ( there's still 5 inches), but I'm hoping this will reduce condensation under the mattress from warm bodies in cold weather. We'll see?

To answer Vic's question, I was pretty decided from the start to do a pull out inside. I have a 48 inch wide mattress from the donor camper, that's in good shape, and I do like the extra room of 48 inches, vs just 36 inches for top bunk, especially if there's two people. The bottom bunk is about 30 inches, and will be just right for one person to sleep comfortably.
 

So still just 48" wide, not 54" (which is what I was hinting at)?    I'm with Bill Harr.... give me a queen size option without the FlatBed!  Note, I did talk to ATC about this option as well, and they are trying it, but finding it twists too much.  I guess the answer is ... so far... stay tuned?!?

Next up, I worked on wiring for exterior marker lights on the four corners, porch lights on the back, and one on the passenger side, and two flood lights on the back end. Additionally, I ran wires from the left front of the camper near the propane box, to the over head bed for solar, and separate ones for roof lights and fantastic fans.

On the drivers side rear, I had to swoop down with wires so the hold down camp screws don't intersect wires causing a potential short. Because I'm doing rigid foam insulation, I tried to stay high in the frame with wire routing, vs more direct path through the tubes.

I also installed boards for the slide out bed support to fasten to through the paneling.

The insulation process was kind of fun, because it seems you get a lot done real fast. I used a table saw, and cut each piece to size so the fit was good and snug. Afterwards, I applied aluminum duct tape over everything for an even tighter seal. With an aluminum frame there will be still be cold spots, but this was my approach anyhow.


Note: We're going fast on the photo progression here folks, as this is the work I've already done. Eventually, you'll be up to date, and my progress will seem slower.

I hope you're all enjoying the ride. I'm weird, but I really do enjoy building things, but as I said earlier, I can't wait to get to use it, hopefully this season. I mostly have just used weekends over the winter, but can now add some evenings with more daylight to keep moving along. I can see why the factory takes weeks or months for each build, and they know what they're doing!

Cheers!

As many have noticed on these older campers, there once was a foam covering over the top of the frame between the paneling and exterior siding. I'm not sure what is used now in the new ones, but I picked up a small role of auto carpeting from Walmart in the auto accessories section. I cut it into 4inch strips, and sprayed the backing with 3M contact cement. I also taped off the top of the camper frame and sprayed it as well. Once tacky, I went around and installed the carpeting strips around the perimeter. It came out looking quite nice.

Ready for paneling inside.

I decided to go with pre finished birch bead board paneling from Menard's in Cheyenne, WY, for about $30 a 4x8 sheet. (I live in Ft Collins, CO). I liked the warm, inviting feel it gives, and it gives a nice contrast with the black carpeting trim. I also added black j-cap molding around the edges, which I'll show in subsequent photos.

Here you can see the nice wood tone/ black window trim contrast. To me the black enhances the wood tone.

This paneling is real wood, finished veneer, and not a vinyl veneer. The advantage is, it won't separate with time, and can have a refinish touch up, if scratched or wears off.

All the panels are screwed on and can be easily be removed without causing damage, should the need arise, for wiring, etc.

Also notice the three rocker switch for each porch light, and one for the flood lights outside. All will be LED.

In case anyone hasn't cut out window openings through paneling before, the first photo shows the router bit I used, the second the full panel removed.

The roller bearing portion of the bit runs along the framing in whatever shape it is. Earlier I showed how I used a plastic strip stapled in the corners to get a radius shape matching the window to be installed.

Of course the paneling either needs to be fastened to the wall, or you must press the router firm enough so it doesn't slip out of rolling along the framing perimeter. Otherwise #€¥^~😬😬 happens! I learned this by experience the hard way.😥

Exterior siding! I can't tell you how exciting it was to finally get to this phase! Oh man!

After searching and checking at numerous RV supply and repair facilities for used or new siding at reduced pricing, without much luck, I found a business in Denver called "The Metal Company". They offer many different patterns, all in white only, with smooth surface, cedar wood grain, or pebble finish. I chose the cedar because, as with the interior of this build, it had a homey, inviting feel to it, which appealed to me.

I ordered a pattern called Mesa, which is a balance of peak and valley configuration. It cost about $2.75 per sq ft, so it wasn't cheap. Instead of also trying to find something used I could salvage (remember I am trying to keep costs at a minimum), I am glad I went this route. This is turning out much better than I originally thought it would. Truthfully, it's looking more like brand new, and in a sense it is.

I used tin snips for cutting the doorway and window openings. I placed the pieces where they would go, and then marked them from behind with a sharpie. Easy to cut the shape when turned over.

To fasten the sheets I used an 18 gauge, small crown staple gun from Harbor Freight. The staple gun easily pushes staples into the aluminum tubing. Pretty easy, really, and like the paneling you see real progress at this stage. You have to be careful, though so you don't get off on keeping each row straight and uniform.[

Interesting that you're using staples. Is that what FWC originally used, or did they screw the paneling to the frame?

I think we are all learning a lot from your build, thanks!
