Crazy idea needs research.
Dynamic roofload can be 100 kg.
Equaling 2 rooftoptents.
But at night, that will be 600 kg static load when the whole family is asleep.
Can the T4 support 600 kg static roofload?
Any proof, experience, failures etc?
Happy camping

Hello,
600kg on the roof?
I think thats not possible...
600 kg for the whole family ? Kelly Family on board?
I think that he has 6 people (400kg) and 2 rooftents (200kg).
But also the size of both tents will be a problem...
Hello Jens Jacob,
I think, the size is not a real problem - if you have two tents who can folded to the side. And I think also, the static weight (if the T4 is standing) is also not a problem.
I have a self made rooftent - and the main board has several (five) bars where themself shoring against the original metall roof. If the T4 to much to bounce - (in case of the weight who moves at the roof - if the people move themself) than you can take four cassis stand under the t4 (at the places, where the car-jack shouldt be)
My main board and the tent alone has 80 kg and at the beginning after the installation, we made a breakfast with a desk and two seat bank and 10 people at the main board (and the food and coffee).
Important is, that the weight can shoring against the metall roof at as much as possible places. If the T4 shouldt have a crash and rollover, the roof have to be a shield for the passengers - and the t4 have more than 600 kg.
Here you can see the bars under the main board who support the board: I think there can you park a second T4 (carefully) (From the breakfast, I haven'T a picture - sorry)
Sorry for my english and
best regards,
Jörg
for static, no problem! But take 4 or more roof girders
