Your the man!!! Great pics. I am sure the undercoating will be fine. Do you think it would be a good ideas to spray some type of sound deadening while you have the room. Not sure about the clearance??? Still curious if they sent a template or if they just give ruff measurements for your cuts and fabrication.
Thanks for taking the time to share your journey with us. I cant wait to see this sleeper rip out of the driveway for the first time.
