Hello.. hope to buy an aliner soon-tommorrow. I was not really keen on dormers but see a unit (Ranger 12) that is nearby (17 hrs) and it has the soft dormers. I seen a pic or two on here and I really like how they open up the space and not close you in so much. I am not a fan of AC so these might suit me better. I have not even seen an aliner, other than driving by and pics. I was wondering ..... does water get in the cracks going down the highway? are they waterproofed well as in deflecting water? do the latches that hold the dormer down lock? what keeps water from getting in at the hinge when erected? How much heavier is the roof when lifting? Any other pros and cons besides ... hear the neighbors more, loss of heat, cross breeze?? thanks for your feedback.
