C class Motorhome Roof Rack Installation.

by Mel
(Whittier, California)

Question: I would like to install universal rails made by Thule, so I can mount cross bars and add snowboard rack for the winter and surfboard rack for the summer. I have 07 Fleetwood Jamboree with a rubber roof.

Before I start drilling, I would like to know where the beams are located and what material are the beams made of. I also would like to know what kind of screws should I be using. Finally, what else do I need to do after the installation is complete so that I don't have leak problem.
Thank you for your help.

Robbie: Installing a rack on a rubber roof is relatively easy. Because the roof is rubber, you do not need to locate a stud because the roof is over-layed with plywood. The plywood is strong enough to secure the rack, so locating a stud is not necessary. Install the rack with the supports evenly spaced (follow the instructions). After you have installed the rack seal the screws and the base of the support with Dycor and your done. Dycor is a good sealer and is sold by the tube. You don't have to apply a heavy coating, it is self leveling but I use my finger making a circle motion to smooth out after applying (Be sure and wear a glove).

Good Luck,

Fleetwood Icon 2008 Roof rack for Kayack
by: Millions2

Hi, I really apprecitate you advice, and I wonder if you could help us; We have a Fleetwood Icon 2008, and I would like to install a Roof rack to carry our kayack. My problem is that I have not been able to identify the structure of the roof. Do I have to drill a hole through the roof inside out and use a boalt with a knot inside the cabin... OR simply screw it in the roof from the outside using stainless steel screws?

Thank You

Good advice but not always correct
by: David K.

As I'm sure Robbie would be the first to admit, not all of the RV makers are as careful as he depicted in this response. I followed this advice carefully only to discover that all that was under our rubber roof was a very thin layer of pressboard. I suggest doing a small tap hole at each site you plan to install a base to be sure that there is some foundation.
