Teardrops n Tiny Travel Trailers

Just working through the planning stages still and was working on the how to add the metal flashing around the base of the unit.
Hopefully you can see what my current cross section looks like. I have read alot about drip flashing added at the base to prevent water infiltration.
I know I have read alot on these forums about different techniques for this. I would like some input on where exactly the flashing gets added and possibly some profile pictures of examples of succesfull use.
Also I would like to know the base way to fasten it .. my planned construction is xps foam with canvas on the outside.

Thanks for all your help.
Great forum!

I install mine after the canvasing is done. This is drywall flashing. I usually attach with 1/2" truss screws. Just start the screws then apply caulk between the flashing and floor then finish tightening the screws down. Wipe off excess caulk.
