How to locate roof aluminum roof frame tubing?
Info: I have a 2020 Thor Daybreak 22GO. It has a square aluminum tube roof frame, covered by a layer of 1/8th inch luaun [sp] and sealed by a TPO rubber roof layer. Styrofoam insulation is between the frame tubes, with ceiling paneling underneath. I have the THOR pdf supposedly on my roof construction. Some of the illustrations [vents, skylights, etc] are not consistent with my particular roof layout.
Modification Desired: I want/need to add a satellite dish [Tailgater] and a single 100W 39"x24" solar panel. I plan to put down rails, anchor them to the roof and then mount the items to the top of the rails. However, the rails are external to my question.
Question: I need to know the [best] ways of locating the aluminum frame . I absolutely want to drill into the aluminum instead of the luaun and styrofoam insullation. Will a carpenter's stud finder work, or is there a better method?
Thank you in advance,
