I'm also interested, but the added weight of my Elemmat bed cover is substantial (plus it's a bit stiff to fold over) and presently use a piece of 1/2"x3" wood cut to the proper length to hold the trunk lid open
I "procured" a set of struts that were destined for the trash at my work and temporarily positioned them to assist the lid-springs. The "rub" is getting them positioned permanently with some type of mounting hardware. It seemed like a simple task until I actually looked at the area where the hardware would be needed (in my case, anyways). The cylinders I tried have mounting-holes on both ends, one of which easily slipped over the end of the spring and could be secured there with a clamp. The other end would need to be secured to the inside of the trunk where there is very little room to work. IMO, the composite of the trunk would need to be reinforced in that area to make the installation fail-proof. I've not done any further investigation into those possibilities.WHY NOT JUST BUY AN INEXPENSIVE GAS STRUT KIT AT ANY AUTO SUPPLY STORE AND INSTALL IT TO HOLD UP THE TRUNK!!!!!!!!
DO YOU THINK THE EXISTING SPRING IN THE TRUNK CAN BE ADJUSTED TO GIVE IT MORE TENSION? Has any one tried to adjust the spring in the trunk?
I may be way-off, but do you mean sorta like the sliding, locking hinge on a piano bench lid? Yep, I can see that as a workable solution. Similar to the hinges on the lid of an old "cedar chest"?A likely collapsible triple hinged mechanism would be needed on either side, sacrificing some trunk space. Think of an accordian type fold in a W shape when collapsed supported by cross braces and springs. It would be difficult to do, but I can see it being done.
