I just don't understand why the A/C is so poorly installed
I just returned from a week of camping which went way too quick
and was cleaning up the camper when I decided too remove the grill covering the A/C unit, and WOW what a poor job of appling A/C tape, I would think that they would have some type of duct working like your home A/C not this exposed spaces and frame work. I think Keystone needs to look at how A/C unit's are plumbed into the roof and fit a poor installation practice.
