Awesome brother, congrats on your journal, it's about time!
on another note I recently picked up Blackvue dashcam and also Power Magic Pro by the same company, I haven't installed it yet but I'm planning to have them both installed so I don't run in to the same issue with draining the battery, the Power Magic is only $25 and works with any dashcam so u might look in to it!
I also like how some people opt for radar in rear view mirror, it looks clean, I remember Kimo gave a link some time ago for the company that does it, I would def. look in to it but if I remember correctly the price was very high, something like $500 not counting radar itself which is pretty much the same price!
Good luck with your project and keep us posted!
