We have a two year old Aliner we bought new back in 2016. It's the expedition with two soft side dormers. We LOVE this unit, but......last weekend camping we noticed water dripping from the hole that the light line come out of, right over the sleeping area, of course. It's only our 5th time taking it out!! There are not bubble windows on this unit so we figured it was coming from either the place where the screws are or the joint where the dormer top meets. I contacted Aliner but the warranty is only good for one year. You'ld think a $26,000.00 camper would have a better warranty. But any way, I'm wondering if anyone else has had this issue.
