See this post. Look for EMAN's posts with pics. He mounted solar on the roof of his T2499 http://www.sunlineclub.com/forums/f6...-t30-8032.html
I will say this knowing how the Sunline roofs are made, you have to mount to the rafters unless you have the walk on roof option. I thought on your Transport there is a rear area walk on roof. But I am not sure if it goes across the entire roof area.
Assuming it stops at the end of the luggage rail, then the rest of the roof is most likely the Sunline budboard roof layed over the rafters. This link will take you to pics of the Sunline roof rafter system. This is a repair post but it has a lot of pics on how the camper is made. http://www.sunlineclub.com/forums/f7...tml#post130979
If you need more info on the roof structure, let me know. I have a T1950 all apart still and I can take pics or measurements off it still. While a different floor plan, the Sunline method goes across about all the campers since the rubber roofs came.
Hope this helps
PS. When you actually mount your solar, that would be a great post to have with some pics. Please consider doing one.
