I know what you mean but I don't have a huge amount of gear so the weight shouldn't be an issue for me.
I don't have a winch and don't plan on getting one so it's just snatch recovery gear for me - a couple of straps, shackles, gloves etc and I thought about putting the jumper leads in there too.
Everything I have is stuffed under the front seats and just floats around so I'm trying to neaten it all up a bit.
