caulking question
Do the outside corners of an aluminum sided travel trailer need to be caulked periodically? Is this a place of possible water intrusion? Thanks.

Technically, if the corner trim is of the new variety with a molded inner flange, it shouldn't be necessary as water should shed between the flange and the siding. Practically, yes, seal everything. Dicor isn't the only game in town. I use Geocel Tripolymer sealant (makers of Proflex RV) and it works out well.
