Continued withthe cowl today. Lots of putting on and taking off, sanding and putting back on. When I was finally happy withthe fit, I made the side cuts and sanded them straight. I then fot the side hinges and drilled all but the botton holes.
Only difficulty I had was the exhaust pipes. They hit the bottom of the cowl and are still very close. Will look at some otherRV's and see what I need to do.
