For me the camera is attached to the left front wheel, so I suppose if you are using a version of RoR other than 0.4.8.0, then it may explode, but I haven't tested that. MrE12AX7 knows about these issues and already has fixed them in the up-and-coming version.

Also, always look through the forum first before asking, because we don't need 30+ threads asking the exact same thing.
The attachment locking system is bound to a command, SHIFT + F7/F8 if I remember correctly. Press CTRL T and you will be able to see all of the commands. Pressing O just allows you to use the backhoe as a crane.

I presume you are using Rigs of Rods 0.4.7.0, which does not feature a universal collision system that allows you to put any loads on a flatbed, because either they aren't compatible with one another, or weren't given proper collision meshes. No map exists (and is likely to stay that way) that...
It is the exact same as every other bus: ctrl 1 to activate ambers, and ctrl 2 to activate warning lights. It is also in the description of his vehicles.
You must have deleted one of the vehicles, because in the newer dev builds, deleting another of the same/ variants of a vehicle with the same GUI will glitch out the textures and/or materials. Afaik, reloading each vehicle normally fixes the issue.
