Columbus construction details

I'm looking for more detailed information regarding the construction methods of the Columbus 5th wheels.

Is it similar to the Cedar Creek 16" OC aluminum stud method? Or is it a solid laminate within the aluminum frame?

Are cut away photos available detailing the construction?

The Palomino web site is rather vague:

100" Wide Body
All Welded Aluminum Frame
5-Sided Lamination plus Front Cap
6" Radius Roof w/ Laminated Block Foam
6' 6" Height (Living area slides)
(5) Heat Ducts Out of Traffic Areas
Snap-in Ceiling Molding -
No Staples or Tape
12-Volt Heat Pads on All Holding Tanks
Laminated Floor w/ Astro-Foil Insulation
R-32 Floor Insulation
R-30 Roof Insulation
R-9 Sidewall Insulation

Thanks

I just downloaded the Columbus brochure and there wasn't a cut away view anywhere.

Actually, your description above, covers it....."5-Sided Lamination plus Front Cap" is exactly what it is. Roof, floor, rear wall, and both sidewalls are laminated. That means welded aluminum framing, rigid foam insulation, and interior panels are bonded as one piece.

The Cedar Creek uses 16" on center aluminum studs and hung fiberglass and interior panels. Also batted insulation, which can compact over time.

I know where Sidney is coming from in requesting some more specific information. A majority of the 5th wheels brochures I had looked at (which was over 30) had cut away diagrams showing the constructions layers of how the RV was built. It is very helpful for people that are more visual than text based. I am one of those that totally gets it on paper, but a visual eliminates any misconceptions.

A cut away view would be nice, but the brochure does give ample information on the construction of the Columbus.

Thanks for the replies but I still find the description very vague.

What materials are used? OSB, Plywood, Marine plywood... tongue and groove? 1/4", 3/8", 5/8" ?

The roof must have trusses... are they aluminum, wood... what are the dimensions? How are they spaced? What is the exterior roof material?

What about the floor joists? Wood, aluminum... what's the spacing? What is the floor base decking material? OSB? Plywood? T&G?

What are the laminated wall components? How is it manufactured?

There are many details missing in the description of the construction.

I don't know much about most of your questions, but I know on some if the palamino line the floor is one solid piece of plywood and I believe it is 5/8".

Ps maybe a call to the factory or the factory rep might help more.

Construction details

I agree with you on the lack of construction cutaways. I would have liked them too. I asked the rep at the show about the details you asked about and this is what he said. Aluminum roof trusses with 6 inch thick(at the crown) solid foam insulation and plywood decking(I don't remember the thickness), plywood-foam-aluminum bonded floor(I don't remember the thickness). Christopher Columbus is associated with Columbus and posts on here and would have better details then me so hopefully he will see your post and respond.

If that is true I'd beware of bonded floor. I have a section on my Cardinal in the bathroom (the only place in the whole coach) and it squeeks like crazy. It feels as if it's separated

My Wife and I have ordered a 295RL. I have emailed Palomino and Columbus several times and got no reply. I even called and left a message and no return call.
