well i have an armorlid and wouldnt expect it to stay completely untouched after pulling that stunt. the damage to the back of the cab actually looks like the frame flexed enough for the bed and mounted brackets to damage it in addition to the armorlid hitting it. ive never had an issue with mine coming open or anything. i have even forgotten to lock it and it never came open. sorry yours sucked.
mines been great. stand on it all the time to wash the truck. oh and if you think for a minute that a TRD or anyone elses fiberglass or other cover would have held up w/o damage, think again. that kind of abuse is gonna break alot. like your truck.
oh and you say the bed is completely twisted form the armorlid cover tearing off? uh doubtful that a plastic cover did that. our beds wiggle and frame isnt that strong to begin with so your bed doin the humpty dance is what screwed your truck up. glad no one is hurt and next time TAKE A VIDEO haha.
