Tinnie on top of Colorado dual cab

I did on my last Colorado on the canopy rack. I replaced the bars with wider uni strut versions. Older dual cabs had plenty of differential flex between bodies and trays hence the advice not to fix to both. I think it would still be good advice.

Hi
I carry a 3.5 Quintrex Traveller on a 2011 Colorado on top of the ARB canopy. Did 2 long trips from SA through the Gulf Country-Savannah Way.
Canopy and interal bars fitted by ARB with a "Flipneasy" boat loader fitted in Brisbane. The total load on the internal bars was within ARB specification. Boat was loaded in accordance with all instructions.
After the 2nd trip cracks were obvious in the tub around the bottom of the tailgate, and the sides of the tub had spread 8mm at the top of the tub at the tailgate.
Holden did not accept any responsibility as canopy not made by them.
ARB did not accept any responsibility as boat was not loaded correctly. They claimed it was too far back, but it was loaded evenly in accordance with their instructions.
Flipneasy offered to strengthen the internal bars.
I had the cracks welded & reshaped the bent rear internal ARB bar myself.
Never again will I deal with ARB. Sell sell sell then run away when there is a problem.
I think the way to go is fit an alloy system down to the floor of the tub but very expensive.

You got really good answers in the other forum you asked the question .

Here is a photo of our set up with the tinnie carried on the canopy only of the BT 50, which is on top of a Rhino side boat loader on heavy duty rhino bars.



The EGR canopy was fitted with the strengthened support rated to carry 150 kgs however the loader and tinny weigh between 100 and 110kgs I think, so well within the limit.

We have used this for the past two years, traveled over 20,000 kms on the last trip alone, with no problems whatsoever.

hope this is useful to you,

regards,

Unless your canopy is designed to support weight on the roof, twist and flex along with the rest of the vehicle without risking it getting damaged I would go with an internally mounted supporting system I use to fit them when I worked at TJM.
