I was not asking for trouble nor have I found any.
1] The gutter tends to clear itself while underway, if any debris even accumulates.
2] First good rain clears it out both ends.
3] Washing the trailer is part of maintenance.
4] About the only way to accumulate debris is while the Trailer is in storage under a tree, then you may have to clean birds nests and bird crap anyway.
5] I have tried the self adhesive drip edge molding and found it marginally effective at best.
I have never had significant debris on the roof but then I do wash and wax the trailer at least once a year.
Here's an image taken a year or so ago, It had not been cleaned in months prior to taking it.
It drains well and is self cleaning when it rains or is towed at speed.
I suppose each application would yield different results, and drainage should be a consideration.
