I was reading another thread that mentioned the RSTV, and someone mentioned using the tether even with a lap/shoulder belt. I have the vest and have read the instructions multiple times, trying to divine whether or not the tether is *only* to be used with a lap belt, or if it ought to/could be used at all times. If anyone knows, I'd love the answer.
Also, my xdh bought a Graco Nautilus to use ff, harnessed for our ds in his standard cab truck (ds is 4.5, about 40#), and has not pursued having the (free) tether point installed. Can someone tell me, please, whether that needs to be accomplished before ds can safely ride in that truck? We've already had some issues with proper installation, so I'd like to be really really really clear about what will need to happen here.
