Since we are talking about up/down problems.....
I bought mine used a several years ago. Took it to the factory and had a new mattress/dinette/curtains made and installed to spruce up the interior. They did a very nice job on it all. We provided the upholstery fabric that my wife liked. Turned out well. Oops. Off track here.
Also had a few other little misc. problems addressed. Asked if there were any updates or mods that needed/should be done. NOTE: I had everything recommended done by them.
A year or two later, after very few uses, I had the top go completely cock-eyed on me when being raising. It was night, and got inside with a flashlight and saw the rear passenger side hydrolic cylinder top had released from the roof bracket (had come undone), and had punched through the ceiling paneling and was pushing up on the aluminum skin about to punch through it. I used my on board plastic interlocking cribbing and small aluminum screw "jacks" to stabilize the top in position at several internal positions while the top was all cattywompus, therefore reducing the internal pushing pressure on the roofing sheet metal. I drove slow (45mphish) almost all night to get to the factory to get it squared away. It was Sat am, and Bryan had someone come in to offload the camper from the truck. The next week they resolved the issues, and they put a patch over the ceiling hole, but the bulge in the roof remains.
Bryan said this is kind of a rare happening, but does occur. They fixed all the cylinders at the top so the cylinders wouldn't unscrew from the brackets. It should have been done BEFORE the problem! I WOULD RECCOMMEND THIS FIX TO ALL ALASKAN OWNERS! Fortunately I was only a nights drive away from Bryan's factory and resolution of the problem. YMMV.
I really like Bryan and he is a peach to deal with, but he did dropped the ball on not suggesting preventing this problem with a relatively quick easy KNOWN preventative fix.....
