Our Bayside Elite came with an ABS roof originally, but at some point in its past, the roof was replaced with an Alumitite roof. When the roof was replaced, I do not think the height was set properly as the upper door latches completely miss the catch, there fore the door isn't held securely. Ive checked under the door and the door seats down all the way. There is also extra canvas that bunches up, so that tells me the roof needs to be raised about an inch. The top is pretty much dead level when raised, so how do I go about adjusting all 4 lifts equally at the same time?
