I finished up the insulation of the flooring, bulkhead and bunk area. Thank you everyone who gave suggestions. Gard, I pretty much followed your instructions to the line. It turned out perfect and I rather enjoyed doing it.
I just took the trailer in and had foam spray insulations done to all the walls and ceiling, so the trailer is completely insulated now and ready for the fir stripping.
Here's my next question, I hope I can explain it so it makes sense. The fir stripping will run horizontally on the the vertical aluminum trailer studs. These studs are approximately 1 x 3, maybe 1 x 4, to get maximum temperature control within the LQ should I insulate over those exposed aluminum studs after I run the fir stripping? They are in direct contact with the outer aluminum skin, there will be heat or cold getting in via those studs... It will be behind the tongue and groove but that still seems to me to be a weak spot in the heat control of the trailer. Keep in mind this trailer is being used in Montana and Alaska.
I was thinking I could cut some 1/2 inch foam board into 4 inch strips and caulk it to the aluminum studs after I do the fir stripping to cover them... What do you think, is it over kill or would this help?BTW, where do I get SS self tapping inch and a half bugle head screws for the attachment of the fir stripping to the studs? I checked the big box stores and they don't carry them. Is it a special order?

It's too bad you didn't have the end of the studs foamed too. The aluminum is a direct conductor of heat and cold. Its inner surface will provide a point that will allow any interior heat escaping into the void before your insulation, a place to condense and pool water vapor.
This weekend we continued the installation of the Exiss LQ, and we covered the stud ends with insulation, hoping to avoid this problem.
We have used a little over two boxes of SS pan head 6 x 1" screws so far on a 4' SW LQ. You can get them here:

If the studs are completely covered, you can install your interior. You shouldn't have any condensation problems.
Well, crap. I thought I only needed to put the insulation on the inside of the outer skin about an inch or so thick. I had it put in there good but its not covered the studs. I thought the most inside of the stud needed to be left clear of the insulation so I could put the fir strips on. The sides of the studs are covered of course, but not the surface that faces the inside of the LQ. Now Im very confused.
Insulation is done... another question.
