I had no problems finding rafters with a stud finder. You'll locate rafter edges when you slide stud finder from both directions towards a rafer. It's extremely simple and accurate! The rubber skin doesn't effect finding studs.
Get on the roof and check it out. No need to call anybody. The rafters on the toyhauler are 24" apart.
I had a lot of problems locating my rafters with a stud finder. When sliding back and forth, the error was more than 1" on each edge, which is not even remotely enough because my rafters are only 1.3/4" wide and 1.1/4" thick. The spacing was 18" on most rafters, and less than 16" on some spots.
