You must drive a hatch-back or a SUV? Trunk covers keep most prying eyes away from gear -- I have both kinds of vehicles and I usually just use the big, floppy hat that I use for emergency roadside stops. The only gripe I have about plastic containers -- is the lid. I never use them and suggest that you don't either. There is nothing as frustrating as trying to get the lid of in a hurry when the container has expanded with the day-time heat.Originally Posted by uclidGood point, although the best way to avoid that is to park in "good locations" and make the vehicle appear that breaking in is just too much work.Vandalism is a concern today and keeping your stuff covered is a good deterrent.
