Which Trailers Have A Double Shell?

[George Nagel]

Condensation / proper ventilation and thermal transmission are two seperate issues.

Francesca, lots of solutions to the dilima, all depending on the construction of the unit. So many varations. i'm not familiar with the construction of these trailers. Maybe just the installation of a couple of computer sized fans for in and out air. A circulation is usually all that is necessary to curb condinsation in any space.

I watch the X-Factor AND have owned both a SCAMP 13' and a Lil'Bigfoot 13'. After watching a few episodes of X-Factor from the 3rd season it became apparent that the Bigfoot required less additional heat (at about 35 degrees) than did the SCAMP.

But, what you pointed out was that there could be a 25% reduction in heater operation and that's a good deal for me.

And I haven't got all that many hairs left to split...

The differnce in these small cubic footage campers, with the various insulations and hull thicknesses is the difference between running your heater rhree minutes or four minutes to maintain. Not anything to worry about.

Lower thermal transmission means warmer interior wall surface temperatures, which means less condensation for the same interior temperature and humidity... so they are not so separate. It's the same effect as double-pane windows.

Gosh Bob, not having ever watched the "X-factor" , I can't really follow. I was just trying to contribute as best I could.

Brian, good point, but i doubt these campers are insulated well enough to make a huge difference. A little ventilation is necessary I think.

[QUOTE="George Nagel;386045"]Brian, good point, but i doubt these campers are insulated well enough to make a huge difference. A little ventilation is necessary I think.,considering the vapor barrier provided by the shell. Simply provide fresh air in and the (moist breath) out. The same problem existe in buildings (homes)...1990's ventilation and 2010's insulation and vapor barriers.QUOTE]

I am not Shure what you meant ? the snooz has an outer shell of fiberglass , and an inter shell of fiberglass and between the two there is a layer of closed cell foam to me that sounds like a double hull I have sample's of snooz hull believe me they are double hull

I had the same initial reaction to Ken's post, Herschel, but decided that he meant that since the O.P. was inquiring about both double hulls and molded in cabinets, the Snoozy didn't answer to the purpose/question posed by the O.P.

IMHO double-hull in the all molded towable means separate molds to make the components. Not an outer hull with components then built in the interior. But truly all parts molded fiberglass that are not removable. More like four molds.. complete molds, not individual fiberglass cabinetry, etc.

X3 as above. Interesting note about the Oliver from their forum

@JuniorBirdMan - That's an interesting consideration. However, when we asked the Oliver folks about what would happen if a leak just happened to occur - they told us that the shells were designed to drain any possible capture of water between them.... "

sounds like a snooz

Good photos posted today of Oliver's double shell, wall, hull, yoke or however you prefer to call it .
