Bob, I had the system on my class c. The struts were fastened with wood screws, the result was the bed was so heavy the screws came out and I had to use a stick even with the struts fastened to hold the bed in the up position. My 2cents.

On our Windsport the bed is to heavy for the strut supports so I took 3/4 inch pvc, cut it to length and put a T on each end. I made a U shaped block of 1x2 wood and screwed it on underside of mattress support for the upper T to rest in. I had to cut the length of the pvc a couple of times to get it right but works good. The T on each end of the pipe keeps it from moving and coming down on my head, works pretty good.
My Challenger came with one lift strut for the bed. Since the area below the bed is the storage area for 2 folding dinette chairs it is required when getting the chairs out or putting them away. Yes the bed is heavy but the strut that came installed is working fine to hold it in place. I may consider adding a second one further down the road as a "just to be safe" measure.
