    D2 Roof Load and GVM

    Can anyone confirm the information I have found regarding max. loads for a discovery 2.

    Max. Roof Load 50kg on-road, 30kg off-road.

    So there goes putting a rooftop tent or even a rack and spare wheel up there. Unless that is for the standard roof rails and not a gutter mount system.

    GVM 2,825kg Kerb weight 2,200kg Allowable payload 625kg.

    By looking at this there is no way I can use my disco for family camping without taking a trailer, especially if I can not put a tent on the roof.

    My initial intent was to put a Wind Cheater alloy rack on the roof with a rooftop tent, awning and extra spare.

    Within vehicle, cargo barrier with divide and twin drawers (one for recovery gear and one for a slide out kitchen) Engel fridge and personal gear as well as 150litre replacement fuel tank and possibly a water tank under vehicle.

    Then there is also additonal items like spotlights, bullbar, steel rims, heavier tyres etc.

    My estimate on this with two adults and two children in the car all loaded up would be around 3,000kg give or take 100kg, well over the vehicle GVM.

    My question is, does anyone have a similar setup on their vehicle?

    If so, any idea on weight?

    I think your math is a little out...

    200kg for the adults
    100kg for the kids
    leave the standard type rubber on the standard rims (you can change rubber on ally rims with just tyrepliers)
    40kg for the full engel
    +60kg for the replacement fuel tank+the extra fuel it holds (assuming that your replacing the main tank and not adding another 150l tank)
    theres 400kg of stuff you just cant get rid of

    you now have 200kg left over

    50Kg for a front bar with a bunch of lights
    20kg for cloths (assuming just a 2 day trip)
    30kg for tent and bedding

    leaves you with 100kg

    30kg for a basic kitchenette draw with a small gas cooker and sink
    30kg for 20l of water
    20kg for basic tools/recovery gear
    20kg for the rest of the draws system

    If you design the draws system correctly it will take care of the requirement for a cargo barrier. but you could swap out the 20kg of the draws system for the barrier.

    and your 25kg underweight on the budget.

    dont forget that the weight of a landy isnt the cut down weight quoted by some other companies but includes the spare, full fuel, and all the kit that comes with the vehicle.

    I came in under 700kg over tare for the cape trip and I had 300l of diesel 40+l of water, engle, recovery gear, an advanced tool kit, air compressor, dual batteries 3 spare wheels, hi milers, HD steel split rims, oils, parts, swag, food, cookiung gear, tarps + me.

    Hi Chris

    Took the D2 (2" lift, AT's on alloy) over the Simpson via the French line (East-West) last August.

    Had a full roof rack (50kg) and a rooftop tent (45kg) and 2 gas bottles (5kg) and bull bag (10kg) on top.

    No problem.

    To keep under the GVM however, I left the rear draws (100kg) the rear seats approx (100 kg) and the muddies on steel wheels (an extra 100kg over 6 wheels) at home.

    Regards

    I've never had a problem keeping under the GVM (2 adults, 2 kids) buit the roof load is another issue. This was the subject of a protracted and heated argument between myself and LRA - the 50kg/30kg limit applies to gutter mounted roof racks according to LRA. Which basically means by the time you've put the rack up there you can carry a couple of bags of sugar and that's it

    having said that we've used a rack and generally carry the second spare, gas bottle, chairs, a bag with sleeping bags, mats and some odds and ends. Personally I'm happy to do this than have to worry about a trailer.

    cheers, Andy

    In regards to the roof load, can insurance refuse a claim if it is found that you have exceeded the 50kg limit (which from reading above sounds as if it includes the rack itself)...??

    Most reputable insurance companies would only refuse a claim if they think that the overloaded roof contributed to the accident. They may also reduce a payout if additional damage is caused by the fact that the roof was overloaded.

    It is highly likely that the maximum allowable roof load weight of 50kg's is more to do with vehicle stability rather than structural strength issues.

    I know it's convenient to have the spare wheel and gas bottles up on the roof but these heavy items significantly change the point at which a vehicle will roll over. Half filled fuel and water containers are particularly dangerous as the load shifts at the slightest change of direction.

    I only ever put the lightweight items such as the air beds, clothing, bedding etc up top. For a family of 5, even this stuff still exceeds 50kg's anyway.

    Cheers
    Martin

    There is no doubt it can take the weight. I usually have the 30 kg tent (a BlackWolf Turbo 300 PLUS), gas bottle, 4WD mats, sleeping bags and pillows in a Rhino bad and I stand on there (90 kgs) to pack it all with no issues. I have a defender 3/4 rack which spreads the weight over 6 legs.

    There is a slight difference in stability but only very slight. And only at higher speeds. No where near dangerous, however..

    my full stop end of story opinion on roof loads.

    DON'T


    Apart from the extra wind drag sucking your fuel out of your tank and side gusts catching them and making you sway they put the COG up and shift it around. Then you have the whole problem of not getting into carparks or wiping them off on low branches or stabbing the tents (seen that once or twice)

    the max weight is stipulated as a load evenly distributed around the center of the roof.

    If you abide by the given limits you dont change the limit of the gradeability of the vehicle.
