I always have a snowboard or two in back and usually some gear. Does anyone have a good way of storing them back there so they don't slide around and bang into everything?

Something like straps, hooks, moelle gear, nets, etc. I have a JKU and always leave the back seats down. Here is what it looks like now and every time I turn I hear a nice thud.

 

You could try a good snowboarding rack I got mine from www.thule.com...their a little pricy but their good quality

 

I'd like to keep everything locked up in the Jeep and keeps it from getting caked in dirt driving to the mountains. Also don't think I'd fit in the garage with a rack :(

 

I run skis and boards in the back as well, the skis just fit inside but the boards I usually flip so the bindings are down and they don't really slide around. You could also make a rack out of a 2×6 with slots to hold your boards on edge. just play around with what works and you'll find something...
