I have a Jurgens Oryx with a pop up roof with hydraulic struts.

The problem is that I have a very dodgy back and I can cause a back spasm quite easily if I'm not careful with the way I lift heavy objects or even twist my torso at a certain angle.

As a result, I am always nervous when I need to lift the roof - the last thing I need is to put my back out at the start of a camping trip!

Any tips on how I can modify my Oryx to make the lifting of the roof easier?
