Full health bar on wrecks doesn't mean its got stuff on it, as it might have already been "looted" by someone else - however, when a server crashes or is reset - the loot usually gets reset too - so whenever that happens and your on....-head to the wrecks

For looted weapons, go to the weapons dealer on a base, and then look at your gus. There is a small blue icon in the top corner of each gun icon (the little picture of a gun). If the two pieces are together then this means its mounted....if you CLICK on that little icon, you will hear a sound, and the weapon will be unmounted (into your hold). Then scroll down and you will see the gun again, but the little blue 'jigsaw" picture is now in two pieces. If you click on this, it will mount it on the FIRST mount available for its class (remount it on ship). If you have looted guns, all the ones that can be mounted on that mount will be the same (showing the little broken jigsaw) -so you can choose which to mount This way you can swap guns without selling them. however, if you die whilst holding guns, you loose them! so don't carry tons of the things - sell the ones you don't need

Wow, didn't check those icons carefully enough, thanks man! And I realized the wreckage thingy right after I posted the message as I went back there and saw that it's health was full again, so it was restored. Better start camping and wait for a reboot, hehe. Thanks again!
