I have a couple questions. I just recently purchased this shack. It is in new condition. 1. What do I use to lubricate the poles, to make them go up and down easier ? They are not bent at all. 2. What is the Model Number of this shack. I was looking for a tow bar for it. But I need a model number. Frabil's web sight does not show the shack or anything pertaining to my shack. Thanks
