Who is an expert on composite panels?

How do I attach items to interior walls?

Again, this is a very open ended question.
The answer will vary based on the type of composite panel, amount of attachment points, the weight that has to be supported and the direction of the forces.

For the specific item you have given as an example... this would likely not be holding a lot of weight and the forces would primarily be in shear.
Tapping plates behind the panel would be the optimal solution, but this would have required forward thinking in the planning stage. Adding these afterwards is possible, but only if you have decent fibreglassing skills.
As others have mentioned already, gluing a plate to the wall and then attaching to that is a very viable option, especially if the load is higher, as the stresses would be distributed over a greater surface area.
That said, if I were installing the item specified, and hadn't planned ahead, I would simply use 4 plus nuts (Google it), as they would easily do the job and their installation is very simple.

Edit:
I failed to mention that another very viable option would be to use VHB tape.

What is you anticipated load?

2 rolls of TP


A ratpack of candy

Or perhaps some soda and water



VHB (3M brand not Chinese knockoff) will hold just fine. If the net had existing 2 sided tape installed, remove that cheap stuff. Once removed (or if it did not have any) wipe down the plastic with some lacquer thinner or MEK (notice I did not say alcohol) and installed the tape. Prep the panel (if unpainted) with lacquer thinner, (hot installer tip, put in place BEFORE peeling the VHB tape and mark with some painter's tape for location AND level as you will not be able to 'adjusted' if you install it non-level), peel the backing on the VHB and install. Give it a hour before adding soda/water bottles (TP and candy can be installed right away). The plastic and/or netting will give way before the VHB or panel give out (well...as long as it is uber-quality Total Composite paneling ).

What is the name of the builder for the habitat? Edit: noticed it was ridgerock

 

[gator70]

I need a ladder. I found this one, minimum purchase 10.

Does anyone want to share the purchase or buy one?

More progress

Most expensive high end builders have interior surface wall treatments. This habitat is mostly composite panel interior surfaces. Some may call this a hospital feel.

Bathroom may have come out a bit large. Forcing the hall to be offset center. Bathroom window could have been smaller. Yet, getting rid of moisture was the main goal. The bathroom has a side exhaust fan, yet no roof exhaust fan.

Due to the complete roof is covered with solar panels, except room for the Dometic RTX 2000 A/C

These build's are hard work, yet fun and rewarding. A DIY build is a resale problem. Everything I did comes with one or two year warranties'. So professional.

Cabover trucks come with very high cabs. This is a challenge to keep the total rig height lower. The advantage is the total length is 5ft shorter than a Ford F550 build.

I did all the engineering on this build.

If anyone wants a habitat, they should contact me. Build time 120 days, and custom requests are possible.

(build time shorter due to all CAD drawings done)

Four season habitat

Built six of these

(weld to subframe - bolt to truck frame)

Subframe made from 5" c-channel

(if anyone needs these, I can build more)

 

[gator70]

Subframe

(5 inch c-channel)

This mirrors frame on composite floor

What do others pay for subframes on their rigs?

Somehow a aluminum flatbed at 14 feet, was not the right choice.

 

[Ferjablito]

I have 5 free torsion points along the subframe

I have 5 free torsion points along the subframe

Interesting - I planned three on each frame side

Earlier I discussed features in a habitat that may be excessive. Features that drive UP the price, and may not be necessary.

Real hardwood cabinets are beautiful - Do I need them on a camper/habitat ?? I guess not

Shown is a "example" how my habitat is equipped to install nice cabinets without the extra expense of real hardwood. (mine is not fake woodgrain, rather solid colors - with nice color scheme)

Also I looked at cabinets in hardwood from rigs built in the 1980's and 1990's, and the style and colors are all outdated. I guess this style I show will not be outdated as easily.

Building an expedition rig, by first listing every part and cost in a spreadsheet, the list will be a mile long.

Somewhere there must be some compromise to reduces these crazy prices.

Planning solar and batteries is hard. And when the weather is raining too much, all that expense is moot.
Yet for me the 12v air conditioner in hot climates drives the technical choices.

Arizona, Utah, Baha sur, camping requires air conditioning

Somehow I believe composite habitats helps with hot weather in calculating air conditioner demands. Possibly you can spend less with that composite insulation.

Unlike Sprinter vans which are a metal can.

This is one of the most efficient and least expensive to use batteries, even so you have to spend a lot on the electrical system to support an air conditioner.

Have you noticed how lithium batteries have dropped 80% in price in the last 24 months?

 

[Ferjablito]

you have to be careful
