G'day everyone..I'm currently running an oztent 270 awning 2x brackets attached to a custom steel rack over the canopy and 1 bracket to Alloy flat rack mounted to roof rack (mounted to roof as per makers specs) My question is around mixed opinions of is that safe? Does it damage the roof of the cab of my ute as it's also mounted to my canopy? I've seen other 4bys also mounted on both cab and canopy.... Just a few saying it could go bad. Currently not flexing and twisting much hard core 4x4 at all just a few rough roads to camp sites. So far the set up remains strong and hasn't budged????
Whatcha all reckon?

Hi Chris,

My opinion, for what it is worth, is that having the awning fixed to two separate parts of the vehicle that can and do move independently of each other is not a good idea. The chances are that you will damage either the awning backing plate, or one or both of the brackets fixing it to either the cabin or canopy on the vehicle.

If it is possible, you might be better to remove the awning from the cabin roof, and attach it solely to the canopy. Of course this may not be possible if the awning is too long. You may be able to “overhang” it forward of the canopy, and slightly rearward of the canopy.

Maybe send a few photos so we have a better idea of what you've got in place.

I did that arrangement to carry our canoe. Not a good move at all. The cab and the canopy twist and flex quite a bit, and independently.
I moved the racks to the cab only and all was sweet.

Cheers

That's not good at all. No way really to attach it either to the front or back, inclusive of each other. Cause if you bring it forward, to balance it, you wouldn't be able to open it out the back properly, and if you move it back, their would be quite a gap, from the rear of the awning to the back of the canopy. I will have to think about the same, in relation to my set up with a Rhino 270 awning on my smaller vehicle. Maybe in your case flexible brackets of some sort, on the rear of the awning, or on the front, although I don't know how you would do it. Would need help, from installers of these awnings on these utes maybe

Hi Chris,

Your second photo is probably the best one that shows what you are talking about. As your awning is a “270”, I assume it opens up 270 degrees. That would certainly put it directly above the rear upper tailgate of the canopy in its current position. Therefore, you must have some way of “holding” the canopy tailgate from lifting the awning up, or do you just let it rest on the awning when it is open?

Moving the awning backwards by 300 or 400 mm and removing the bracket from the ute roof rack whilst would create a gap between to end of the canopy roof and the edge of the awning, when the canopy tailgate was open, the tailgate would “close” this gap. It may not prevent all the rainwater if open when raining from getting under the awning, but it would certainly be better than no awning.

One possible solution could be to use sturdy flexible bobbin type A mounts underneath the rear bracket where it connects to the roof rack.

See here for an idea as to what I’m on about.

Bobbin Type A

These can be sourced from a variety of places I only linked to the above as a means of showing what a Bobbin actually is.

Using two of these would at least allow a limited degree of flex between the vehicle mounted rack & the canopy rack without loading up the awning.

If the correctly sized bobbins are used they should provide enough support when the awning is deployed.

The hard mounted front brackets should be more than sufficient to carry the majority of the awnings wind loading whilst the vehicle is in motion.

Those bobbin type A mounts would not have anywhere near sufficient flex to cater for the flex in a twin cab chassis.

Maybe not, at least they would offer far more flex than what is in his current set up!

If more flex is required then perhaps annular mounts would be a better choice.

If there’s more movement between the cab & the canopy than what they can handle then I’d be concerned about the canopy hitting the cab.

Depends on where you plan on taking the car. Staying on the tarmac it will most likely be fine, any offroading on suspension flexing roads may see some movement. As others have mentioned there is quite a bit of movement between the cab and tub.

Does the awning need the front mount to operate or is it only for support while driving?

I have seen some awnings "resting" on the front roof rack, basically same mounting brackets as yours but the front one isn't actually bolted to the front rack. It just rests on a piece of thick rubber which takes the weight while driving but also allows it to move when on rough roads and the cab and tub are flexing independently.

IF....Both cab and tub are rubber mounted to chassis, it shouldnt be an issue, but keep an eye on brackets for signs of cracking. If the rear is a tray, with canopy, trays are not usually rubber mounted, and this setup will cause eventual failure. You dont say how the custom rack is anchored, i am summising to the canopy roof, but i have also seen through the canopy to the tray.
