I put track lighting over the counter in my Keystone Montana. If you go to Home Depot/Lowes etc. you can buy an inexpensive electronic stud finder, I think I paid less than $15. It found all the structural members in the ceiling as well as the walls for other things. It also works good at home. It made the job very easy.
