I Took my Boat to Cope Nc Phetres Marine at Bell Acqua. They have worked with my insurance company before, they are very well known and have a good reputation in the area.
Cope has not worked on a Toyota before.
I'll let you know how they do.
Your instincts are "right on" about the former Toyota dealer here in Sac. I can't recommend them.
I'll let you know when I'll be out on Oroville, I'll need to throughly test the boat before our Houseboat trip.
Do you usually launch at Bidwell, Lime Saddle or the Dam?
