Two separate limits apply to anything you put on the roof, and the smaller one wins. The first is the vehicle's own dynamic roof load — the weight the roof may carry while the truck is moving, rack included — and the club article cited below gives that figure for this generation, alongside the much larger static figure that applies only when the vehicle is standing still and which the club is careful to attribute to a rack maker rather than to Mitsubishi. The second limit is whatever the rack you buy is rated for, which is a statement about the rack and never permission from the vehicle. Take the smaller number, subtract the rack's own weight from it, and what is left is the cargo you may actually carry up there.
What it needs first
Nothing else has to be done first.
What it breaks or affects
Everything below is a consequence of fitting this, not a reason against it. Read it before you buy, not after.
| System | Consequence | What happens |
|---|---|---|
| Body | Has to be reset | The club article cited below is explicit that the Generation 3 dynamic figure covers the roof system and the cargo together, so the rack's own weight — which the rack maker publishes — comes off the allowance before you load a single item. It also separates that dynamic figure from the far higher static one, which applies only to a stationary vehicle and which it attributes to the rack maker rather than to Mitsubishi. |
| Suspension | Has to be reset | Whatever goes on the roof is also weight the springs carry, and it comes out of the same payload budget as the people and the fuel — the difference between the curb weight and the gross weight in the second citation. A roof load does not get its own separate allowance just because it sits above everything else. |
The honest tradeoffs
A roof rack is the cheapest way to make a Montero look like it goes places and the most expensive place on the truck to put weight. The dynamic and static figures in the first citation are not two opinions about one number — the gap between them exists precisely because a moving vehicle loads its roof differently from a parked one, so a roof-top tent that is fine overnight can be over the limit on the road. The rack's own weight is charged against the vehicle limit before you have packed anything, and the weight you do pack is also spent out of the truck's total payload, which is the difference between the two weights in the second citation and is shared with the passengers, the fuel, the drawers and the second battery. There are costs that never appear in any table either: the truck is taller than a car park expects, the wind noise is permanent, and the fuel penalty is there at every speed. Load ratings are safety-critical. Weigh what you are putting up there, take the smaller of the two limits, and note that the figure below comes from an Australian club reading Australian documentation — if you cannot find your own market's owner's manual figure, ask a qualified shop rather than assuming the number transfers.
