N2T Posted August 30, 2015 Report Share Posted August 30, 2015 Sounds like this trailer isn't going to move much. So why build a trailer? Link to comment Share on other sites More sharing options...
4Girls&aMan Posted August 31, 2015 Report Share Posted August 31, 2015 "R30 walls and floor and R50 roof would work..." Are they making anything that has that kind of rating in a "compact area" like our walls and ceiling? I suppose they do for the space shuttles, but I don't know how thick those walls are. http://www.jlconline.com/how-to/insulation/next-generation-foam-board_c I don't see that the product being used on the project I'm participating in is listed at the above link, but they tell me they are consistently getting R30 with a 1 inch thick package. The only hitch is that you can't allow any holes in the package since it essentially relies upon a vacuum. 2007 2L Freightliner Century Condo, 14.0L Detroit, QD 60002013 Space Craft Link to comment Share on other sites More sharing options...
Lou Schneider Posted August 31, 2015 Report Share Posted August 31, 2015 If you start with a rectangular 13'6" tall box, you'll have room to stack the ceiling insulation to get a R50 value. And allow for a thicker floor to get your R value there. But this means no roof accessories like air conditioners and vents. The problem comes in the wall thickness needed for high R values - at least 2x6 framing which cuts down on the available width in the living space. You can alleviate this by using large slideouts, but then you're looking at maintaining the insulation around the slide lip to wall transition, otherwise you risk a thermal leak.

This product looks interesting - a conventional polyurethane sprayed foam would likely suit our purposes and we could work around the extra 20 sq ft the wall thickness desired would use up.

noteven Posted September 1, 2015 Author Report Share Posted September 1, 2015 Chemical based spray in foam can give those r factors. But there will be health issues. Would a heat recovery ventilation system counter the health issues? "Are we there yet?" asked no motorcycle rider, ever. Link to comment Share on other sites More sharing options...

N2T Posted September 1, 2015 Report Share Posted September 1, 2015 Build a pole shed in the cold climate, put the trailer in that. Buy, and live in, a manufactured home for the cold location. Or rent when you need to get stuck in the cold, and find a commercial place to store the trailer. Or leave the trailer in the south and fly home to the great north and just rent. Trying to fulltime a cold season -- that is this cold -- in a trailer is silly. It's just too much of a compomise. You could make is work in a boat, but the constraints of something that needs to roll down a road lane are too much. Link to comment Share on other sites More sharing options...
sclord2002 Posted September 1, 2015 Report Share Posted September 1, 2015 I just priced the Timbren system that ataches to your existing axle and it would be approx $3400 to $3800 for a 2 axle trailer [parts only] then you would have instalation costs. I really like the Timbren air suspension but the price is more than I care to invest at this point. Jeff, the person I talked to at Timbren was very knowledgable, cordial and helpful. Sigh.....too many projects and not enough money for them all. Not really complaining, just stating a fact. Charlie Don't ever tell a soldier that he doesn't understand the cost of war.

greenacres Posted September 1, 2015 Report Share Posted September 1, 2015 The problem with beat recovery systems is it uses electric strip heat to prevent the exchanger from frosting this for me anyway is not feasible since we are completely of the grid. Chemical based spray foam system off gases a formaldehyde that is supposed to be OK I just don't believe it trailers are just too small to take any chances. I opted to just over size the heating system and install a back up heating system as well. Link to comment Share on other sites More sharing options...
jkennell Posted September 1, 2015 Report Share Posted September 1, 2015 I would be VERY interested in the price of those Axleless suspensions, not for the RV, but for a flatbed design. You call them, find about what a 7K 4 wheel system would cost!! No camper at present. Way too many farm machines to maintain. Link to comment Share on other sites More sharing options...
noteven Posted September 1, 2015 Author Report Share Posted September 1, 2015 Hi Jeff CIL I'll give them a buzz and let you know. I want to thank everyone for their input and ideas. I kind of suspected it was a stupid concept to pursue. If you can imagine I kind of wondered if this concept wouldn't sell on a limited commercial basis to full timers who need to live in a bit cooler winter season and are tired if the propane and electric heater bills and discomfort. We are looking at other avenues. "Are we there yet?" asked no motorcycle rider, ever. Link to comment Share on other sites More sharing options...
