In regards to the tenting not staying in place, put some threadlocker on the bolts. It does wonders. I got some threadlocker to stop my adjustable bar stool feet from slowly unscrewing themselves and getting wobbly every week and it's easily the best purchase I've made all year. Anytime I see a loose door knob, chair leg, tripod mount, or adjustment screw, I throw some threadlocker on there and never have to tighten it again.
