Where there is a will, there is a way! Here's my PA12 using a Yakima Whispbar to Thule Slipstream setup. I want a truck too, but this works for now. I would have gone for the PA14, but IMO that's pushing it for my particular roof top setup.
As for bow/stern tie down straps, I use them for 2 reasons. For the weight and cost of a PA, any additional straps to help secure my investment is reassuring. This is especially true when traveling long distances to SD/Mammoth. Secondly, I feel an obligation to not endanger other motorists around me in case of an accident. The PA with forward momentum will certainly cause physical/bodily damage.
