You can't DIY that in Idaho in winter outside. A shop could do it if you trust them to not do a crappy job. This is assuming that the gutters are cracked and leaking but we don't have enough photos. I would suspect so since the roof rack mounts will wreck the old caulking.Could I DIY that or drop it off at a shop within a week of when I get it into Idaho? I am parking it outside... :/
