Came across this thread after doing a Google search for gas struts used on swing out tire carriers. Good info. Will be refurbishing a first gen Slee rear bumper c/w tire carrier I picked up last weekend. Will be adding gas strut or damper (now that I have read this thread), rear work light, and positive latch mechanism. Have reservations about visibility, rear accessibility, and durability (resulting from vibration). As others others have said, I don't see any other option for a full size spare (315 for me).
