Next, I will start insulating the sidewalls.

In the meantime, I installed a first layer of 1” polyiso insulation board in the ceiling. The panels I cut fit very tight between the 1” roof bows. Consequently, the insulation board is flush with the roof bows.
I did not install the insulation with any air gap between the insulation and the roof skin My reasoning is that:
1. the dead air space only has an R value of R1 and the insulation is about R6,
2. Steel roofed pole barns around here are all built with no air gap,
3. If there is any condensation, there is nowhere for the moisture to escape (because the cavity is sealed tight),
4. I do not see how any moisture laden air can get into the cavity (because the cavity is sealed tight).
5. The polyiso is rated for 600 degrees F.
I installed the foil face side of the foam board against the roof skin but don't think it really matters, since there is no radiant barrier effect without at least a 3/4" air gap. Also, maybe the foil facing will hold up better laying against the hot roof than the plastic coating on the other side of the board.
I plan on installing 3/4" furring running lengthwise on the ceiling, to accommodate another 3/4" layer of polyiso, followed by another 1" layer of polyiso, for a total of 2 3/4" of insulation.
One technique i used to cut the panels was to measure the width between the roof bows in five different places: one at each side, one in the middle and two between the previous measurements. Then I transposed those dimensions onto the foam board with a long straight edge and a pencil. Ink pen would not work on the plastic side and the wet ink just smeared if touched.

So, let's recap.
New Featherlite trailer, 3 full dress Harleys, house the country....Nope. You can't be married with children.
1. Not planning for AC in trailer. (or house?)
2. Didn't mention installing bathroom as first order of business.
Naw, not married.
Well, How'd I do? Been taken lessons from my cousin, Dick McTracy.

We didn't have no fancy tent poles growing up. Just had to use a couple tuba fours nailed together in the shape of a "Tee"
We called em' deadmen. Pretty good helpers though.
So, three bagger Harleys'? Now you are just showin' off. No man in the world can ride 3 Harleys. Cept' this guy.

I'm sure your roof is aluminium so it needs some light prep, just like painting a car etc. A mild acid (white vinegar water solution) and light scotchbright scuffing will be plenty to provide some grip for the paint. You don't need to use any elbow grease.

You could use some 2" wide Blue Painter's tape and some of this stuff,

to protect your CT from harm from the TPS and leave it on so any drips or spills
won't create problems. Just a thought.

That metal should be nearly pristine up there. The trailer can't even be a month old.
I would avoid the TSP, you don't need anything aggressive for new metal.
