That's a good idea. I was also toying with the idea of either lifting eyes at the top corners, or grab handles lower down on the corners.

Insulation only slows down equalizing with outside ambient temps.

Makes the use of active heating or cooling much more energy efficient.

But not magic.

Magic is travelling to follow the 60's.

For ventilation, MaxxAir or Fantastic Fan.

Thanks. I have read a bit about Fantastic Fan. I will look into Maxxair.
Still wondering if I really want a ceiling vent, or just side vents mounted as high as possible.

You need active ventilation, high CFM for when needed.

Where / how you mount it, up to you, best if the intakes are opposite the outgo in more ways than one.

Fridge, stove, batteries should be taken into account so all needs are accommodated synergistically.

Thanks. We plan to start out super basic, just a “hard tent,” but I’m well aware that two people inside a tight tent can cause a lot of condensation. Life here in the Pacific NorthWET seems to revolve around keeping warm and dry. :)

Guys I went over to my friends Guitar making shop ( New Orleans Guitar Company ) … He showed me a hatch he made for his new boat … 1” foam with fiberglass on each side …. he remarked “ I can stand on it “ … and proceeded to do so placing it between two boards on the floor ….the 250 lb test … No Problem … Even I was surprised ... :o It wasn’t pretty but it sure was strong …. and Light … :thumbsup:

Still thinking about that ventilation. Yesterday, in Home Depot, we were looking around. We had decided that the low budget approach was to make our doors by cutting them out of the foam, lining the opening with wood, reducing the door a bit, and putting enough wood around it to let us mount hinges and latch (I need to do a bit more figuring for a door seal). Windows could be cut out of the door and added, as we found something affordable that fit.

As we walked by a large display of pet doors, Kathleen said “this is going to sound stupid, but would any of those fit?” We looked them over and discussed the issue of adding screen and the window (I have some plexiglass around the shop). Pet doors are likely not an answer, but it was a good reminder to think outside of the box, to keep our eyes open for more than just things clearly labeled as windows - and this was just before we went to Habitat for Humanity. We didn’t find anything for the foamie project, but I did get a 6’ baseboard heater for $2 and Kathleen got a huge and very desirable $60 cookbook for a buck. I sometimes wish we lived closer, so I could check that place more often. But most of the time I wish we lived even farther out in the sticks. :)

Couldn’t resist buying another five (4.92) of Glidden Gripper. We believe in stocking up, and we do have houses to maintain. Decided to do the waterproofing of some wood we have, so bought three gallons of mineral spirits and a gallon of oil based polyurethane varnish.

When looking at foam in HD, we saw PL300 foam glue by Loctite. I know the standard here is Gorilla Glue or Gorilla Construction Adhesive. But I wondered how this stuff, which is advertised as specifically for foam, would compare for foam to foam joints.

Any thoughts on that PL300? Costs half as much as Gorilla construction glue, and it claims to be specifically for foam. But we are not building houses here. Which one will have a bit of flex while bouncing down the road? :thinking:

Dunno, but I think so much flexing in the surfaces, Not a problem if the edge joins are rigid.

As long as they're damn strong.

And then consider a Foamie camper is a LOT more Flexible than a conventional trailer …and being a LOT less weight than other trailers , it really doesn‘t rebound ( bounce ) liike a heavier trailer would … Naturally trailers intended for off road use would benefit from a proper suspension for the intended purpose .

Good point. Less weight, less stress. And, since the real strength comes from bonding the fabric to the foam to create a composite, I doubt it matters much which of these methods of joining the foam boards is used. I’m just curious which of the glues is better. I have been impressed by original Gorilla Glue. If you expect and allow for its expansion/squeezout, it does have the ability to push itself farther into the wood than I could reach when applying it.

I would suggest that you avoid a miter for the wall to floor joint.
Although there is more surface to glue, the tendency to slide out
of place and possible greater pressure on a point are undesirable.
