Roof tent on an Evoque: good or bad idea? - Mattyw - 09-08-2014 06:29pm
Hi all
Considering buying a roof tent for our Evoque that has pano roof, roof rails and cross bars.
The tent would be a Maggiolina or similar see: http://www.boab.biz/ah_tech-maggiolina.htm
My issue is this: the roof tent manufacturers advertise their tents on top of LandRovers, and Landrover seem to support the vision of this kind of kit/exploration.
But can an Evoque take the weight?
The roof rail specs say a limit of 75kg, or 165lb.
But that's one grown adult, without the weight of the tent, around 30kg.
Even a Defender has a weight limit on roof of 150kg, which still a tent and only two v light adults.
Not a tent and average man and women.
Some tents are advertised for use by 2 adults and 2 children.
Has anyone fitted a roof tent to an Evoque?
Any issues or answers for the discrepancy in weights?
Thx all
M

Well, it's certainly a novel idea, sleeping on the top of your Evoque.
Leaving aside the fact that you'd look completely ridiculous, roof loading is an issue. You are correct that the maximum roof loading is 75kg but that is more to do with the strength of the mounting points and the roof rails themselves than the underlying strength of the roof which has to be strong enough to support the car upturned.
Since you probably wouldn't be occupying the tent while the car was moving, it might be that a higher stationary load is possible but keep in mind that these are static loads.
If, however, you decided to engage in a little rumpy-pumpy, the resulting rhythmic activity would increase the peak dynamic loading on the roof rail mounting points and if the frequency of excitation resonated with the car's suspension, things might rapidly get out of control leading to structural failure and an affirmative response to the question: Did the Earth move for you?

Hi Mark,
Now what page is this information from the owners manual?

Whilst saying 75kg, this will be dead weight of a load on the roof stationary. Once at motorway speeds the load will have an aerodynamic effect which will probably be a down force (assuming a roof box from Halfords) which might add another 100+kg?

Well I'm sure it wasn't on the list of design and performance criteria when the roof bars were designed...
Just imagine, given Posh Spice's involvement with the Evoque and their habit of naming their children after where they were conceived, we might have had one called "Evoque Victoria Beckham Special Edition Roof Tent... Beckham".

Its got a pano roof,I wouldn't put a fag packet on top of the car.

Mattyw, this might be a good query to bounce to LRCS, Pete. I'm sure he will know who to direct queries like this to. The roof of a car with the panoramic roof must be just as strong as one without for the reason mark-n gave - the issue is what it the weight loading that the roof rails and their fixings take. I would imagine the roof slope might make for a weird sensation once in the tent, especially in a Coupe.
Regarding info suggest you email Nene Overland who are specialists in preparing Land Rover products for expeditions and sell several brands of roof tent, mostly for the larger cars in the range.

This doesn't touch the car roof itself, so Pano roof or not is pretty irrelevant, unless you puncture the bottom with something sharp or slip getting in, or you overload it and deform the roof at the mounting points which is unlikely, most likely is the bars deforming lowering you onto the roof! It comes down to the strength of the roof bars and the mounting points surely which will likely be the same on both models and will withstand 75kg of moving weight which will be a lot heavier at worst case. No pillow fights or jumping on the mattress or other things as mentioned above!
Hope you don't sleepwalk though!

Well that will add a new dimension - instead of "Not tonight, I've a headache", we can expect "Not tonight, the roof bars won't take it".
