We had a trailer like the pic in advertisment. I really can't say if it helped with lifting but helped holding bed up when you dig something out.

Unless you went with ridiculously strong struts, they do not help that much in the lifting of the bed. If you go with over rated struts the platform will become harder to close and you would most likely have to put some sort of catch on it to keep it closed. (I had this problem with the tonneau cover on my old truck. I parts guy sold me the wrong struts, you needed two men and a boy to close it and if you weren't careful opening it you could do yourself a grievous injury).
You still have to over come the weight of the mattress, this has a lot to with the hinge in the bed platform and having to over come the friction of the mattress as it slides along the edge of the platform.
Not saying don't install a set, just don't expect them to be total solution.
Perhaps a better solution for you would be an electric motor. About 10-12 years ago I was looking at motors and worm drives for the tonneau cover. Not cheap, but effective.
