The two gas struts on my fibreglass Raider LoRider tonneau are pretty worn and it takes a lot of effort to lift the cover on my 2004 Supercab F150 with 6.5ft bed.

I'm not sure if the existing struts are original or swapped by a previous owner so I'd rather not rely on them for spec.

Does anyone know the weight of this tonneau (or a similar one) so that I can then calculated the struts required to open it up?

 

Can anyone help?
