I am pretty happy with the seal around the bottom of the walls but have some long term concerns at the front and rear.
First and exploded view of the side wall.
Because I could wrap the dicor over the PMF and under the floor with tar to cover, I see zero issues here but on the front and back it's a little different because the trailer frame is flush so no way to do that.
Here basically the trim and PMF end right where the trailer frame is. The 2x3 is glued and sealed but where you see the asterisks I am concerned about water right over the trailer frame where the PMF and trim ends.
Should I try to seal it the best I can and risk trapping any moisture or leave it so any potential moisture can dry? If I tried to seal is I would do the outside and underside. If that's the option, what product? Needs to be black.
