First of all, this is a great video. Thank you. I really recommend you get a nice Bosch jigsaw. Nobody and I mean nobody in the woodworking community uses Black & Decker jigsaws. Take care of yourself, you deserve deserve better. At marker 4:26 you were trimming the wall panel for the trim ring. I would consider installing the trim ring and then using a router with a bottom bearing up cut spiral bit to trim the wall panel right up to the trim ring. What is a P clamp? How do the panels actually attach to the walls? All screws?

Thanks for the video. We’re going with a Transit 148, so we’re looking forward to that video

Very helpful!

Thanks for this video. Wish it was more detailed and terms were explained for the newbs (aka me).
