Roof, Seals, and Seasons
Water is what kills a trailer. It gets in through roof seams, around vents, under slide seals, and through a dozen screw heads nobody has looked at since the dealer lot. It freezes in lines that were not fully drained. These guides cover sealant selection by seam and roof type, leak hunting, winterizing both ways with quantities, and the spring dewinterizing routine.
If you only read one thing before your first fall with the rig, read the winterizing guide and use the antifreeze calculator.
