Otter has had some issues with the lodge owners in which the long top fixed wind pole is too long. Contact Otter and they will get you set up with a new wind pole. As for the frame bars having a lot of flex, there is a black plastic cap on the end of the smaller frame bar (the one that slides in and out). The caps will get stuck in the elbow of the frame bar, thus making it flex a lot. If you remove the smaller frame bar and there is no cap, it is stuck up in the elbow. You can poke a hanger through there to get it out and bend the end of the bar in with a punch and hammer, or contact Otter for some new caps. This issue will be fixed on next years shacks.
As for the tight fabric, I’d set it up and redo the trim lock. An inch makes a big difference. Especially if it’s loose in the back. Just take the slack out. The velcro does not always need to be wrapped tight. There is acces velcro there sonit can be used for adjustments. If the front is saggy, make sure the bottom velcro is wrapped tight as this will bring it down more. Also doesn’t hurt to pull the canvas to the bottom of the frame bar when set up.
As for the xt cabin owners with the loose canvas- What I have found out is that I can set it up perfect with everything nice and tight, but the crossover frame bar doesn’t reach the floor clips when I go to switch it over. Not without loosening the front wind pole, which makes the canvas saggy and really loose. Not a problem on the pro model, has to do with the bracket and the height of the pro sled. Otter is working on redoing the bottom frame bar clip to make it offset to the inside and then come up a ways so the frame bar will fit in the upper corners of the canvas. This will also make it so all the bars lay flat like the previous models. Which is a huge deal to the cabin owners because with the way clip sits folded up now, we can’t close our tonneau covers. Otter is aware of this and the new clip should be out for next years models they are hoping. So stay tuned and make sure to hit them up at the beginning of next season.
