For those of you with the Truxedo Bed Covers, I want to know exacly how secure this cover is. I am a little confused. From what the website leads you to believe, the cover is very secure with a locking tailgate (like the Titan) but part of me is wondering how this can be when the sides are held on with Velcro and the cover itself is made of a soft vinyl type material. Couldn't someone just walk up with a knife and cut right through it and steal the contents or seperate the Velcro on the sides to gain access? Please help. I need reasonable security on a daily basis but I need unobstructed access to the bed for my ATV. Thanks in advance!
