Awning installation

I recently got a 19' two axle, 86 Road Ranger TT, after a good overhaul the only thing that this TT is missing is an awning.

I have no idea how to start this project, do I have to somehow locate the inner framework (studs)and secure the brackets to them ?

This TT has an aluminium shell, will the fittings be secure enough without going for the studs or simply fly off at 55 mph ?

Any help would be great.

Thanks
