Got a roof rail from Fiamma USA out of Orlando. I had to be put in a container and shipped from Italy, as they had none in stock. It was about $800, its about $550 in the UK - but its only way I could get one, so I just paid.
Easy setup. I ended up having the rear section farther back (back edge in line with start of upper red tail lights) as I wanted to be able to get a better angle if I tied anything to it and avoid the top edge of the van. With that, I ended up cutting 17" off the front sections (I have a 136WB HR), if you line up the rear bar with the mounts, you might have to cut about ~20". Dry fit it for look and Google the Travato and Ducato setups online for some ideas and preference.
10mm open wrench
Rachet screwdriver with a #2
phillips tip (self tap screws) and a T25 tip (horizontal bars)
Hacksaw w/mitre box
-I put on the mounts first, worked well and used some lapsealant on the inner contact area (install said to used Sika). The outer contact comes with some nice rubber 3M pads - not sure why they just did not provide thinner pads for the inner contact surface of each mount). This was easy, you need a 10mm open wrench.
- I climbed on the roof to put the rails on, was safer to me than the ladder
- You can do the self tapping screws by hand, but just need a good 50lb of muscle force. Otherwise tiny pilot holes would work.
- I started with the back rail, measured the distance on each side then locked it in with the self tappers into the rear mounts.
- Then be sure to put in your brass square backing nuts that go in the rail before you connect rail into the center mount.
- I put 2 of the horizontal bars in the back half, and the other 2 in the front half (as seen from the center mounts). I was able to avoid my flexible solar panel that's 3M velcro'd to the roof and the MaxxAir fan.
- You might have to use a come along or strap to pull together the rails in the front about 1/2" so you can thread the screws for the forward most horizontal bar. I was able to get mine after doing in the middle horizontal bars.
- Don't super gorilla the screws or you will strip out the soft aluminum, plus you might have to move bars later.
Hope that helps
