...and read on for more on how we got this setup set up:
The Overlanding kit for my XC60 T8 is starting to get serious...after endless searching and researching, I put my hard earned clams down on a pre-order sale of the new Falcon RTT from Roofnest.
At just 6.5 inches thick and an aluminum shell it's the thinnest and sleekest RTT out there, and mine arrives via truck freight tomorrow afternoon.
To get all ready for it's arrival I put in some serious mucking-about-in-the-garage time today figuring out the rake of the roof-bars with the air suspension in different settings. The tent is 85" long, so after you move that length forward enough to clear the rear hatch when open, it'll end up poking out above the windshield substantially...I'm probably being OCD but I would think it's probably best not to have that pointed upwards into the slipstream like a new baseball cap (and look similarly dumb).
Now the following measurements are admittedly half-assed.
With no reasonable way to measure from the top of the bars to the ground, I measured upwards to my garage ceiling, so we need to trust that it's flat and level and that my hands and Mk. 1 eyeballs made the measuring tape stand reasonably close to vertical.
Let's start with Pure mode, the suspension mode I prefer to travel in, and this will be the baseline, with the roof bars mounted at the official default positions as per the manual.
The difference between the two bars in Pure mode is .4", the front bar being .4" higher off the ground than the rear bar. Annoying.
Then we have, and again with Pure as the baseline:
Mode....... Front / Rear
Parking..... -1.2" -1.1"
Hybrid..... +0.3" +0.4"
Power....... -0.3" -0.1"
AWD....... +0.3" +0.4"
OR......... +1.8" +1.8"
A couple thoughts on that data...Pure and OR have the same rake, while in all the other modes the rear is higher, especially Power where the rear is .2" higher up than Pure mode.
Also I never realized before that Hybrid and AWD mode have exactly the same height and therefore ground clearance. I thought AWD was a little taller and then OR was super tall...just me?
Anyway, the goal then was remove that .4" of rake, and also spread the bars out to better spread the load (suggested distance between the bars is 36-42")
The trick was to move the front bar as far forward as possible while maintaining proper rail engagement, this brought the front bar down substantially, and then I placed the rear bar 40" back from the front bar:
This arrangements shifts the height balance by a full .5", making the rear bar juuuust slightly higher than the front.
Next problem I may have is width...the Falcon RTT is 50" wide, which is about 5" wider than the factory bars.
Not a structural problem, but if you look closely at the pic see how the end-caps fold over the bars?
I may need some sort of .25" shim in there so the bottom of the tent is properly supported across the full width and the locking bar caps don't get mashed.
More to come stay tuned! Aiming for Labor Day weekend for our first excursion if we can get everything sorted out in time.
