Found this thread last night and have read practically every page of it. The goal is to build something very similar as I've always love the "teardrop" style but have been wanting something more off-road capable.
As has been said many times before, nicely done.
But if I have one piece of advice for both you and Nicole, it's to wear a respirator when working with Bondo, or any other product like that, during application and sanding. Not a dust mask, but a proper respirator.
While you may not notice it now and you might think you have great ventilation, there is nothing good about getting even a small amount of that stuff in your lungs. Having lost my father to asbestosis from working on brake linings, I cannot stress protecting your lungs enough. They didn't know any better back then. We know a lot better now.
Keep up the great work.
