Ben: The helper springs seem to be all over the map....mine are around 23" long with a rate of 12 lbs/in; I think Mountainbikeroamer's are way shorter. I pulled one out and measured it the other day because I'm toying with the idea of replacing them with gas struts. Perhaps you should consider this mod too......I'm sure your brother can help with the design.
Thanks for the spring specs, I will start looking around for something similar. Keep me posted on the gas struts, it sounds pretty intriguing.

Old roof with solar and no helpers is no joke, super heavy. And thats before the cargo box goes up top haha.
Yeah it's doable right now, but not as easy as it should be. With more weight being added I will definitely need the helper springs.

I can get some photos of the entire helper spring setup / get some measurements of those springs while it's apart. (The diameter is pretty easy to figure for yourself already --- they're basically **just** narrow enough to fit into the C-channel that all the penthouse roof x-brace bottoms slide fore/aft within.)
That would be awesome. I understand the general concept but pictures of the whole setup would be very helpful.
