It would be near impossible to do any damage to your vehicle with a taser. But, be forewarned that Tasers, and stun guns are in most states considered under the same laws as regular guns, so careful in carrying them. I think these laws are sort of ridiculous comparing a stun gun with my pistols, but check your state/city/county carefully on this one. Good idea to take a self defense class, maybe get a concealed weapons license even if you never plan to own a gun. The courses can also help you in court if you ever do stun someone as you will know how to explain yourself so you don't find yourself in a legal hassle you don't deserve.<br> <br> Odds are if fired the prongs will impact either a non-conductive area such as wood or vynil in your RV, and heaven forbid if they impact steel or something conductive, there is a very good chance they will not penetrate and stick to it. No penetration means it won't be stuck in it, so it can't shock it. Even if you manage to hit it into an electrical system the odds are that since electricity moves thru the path of least resistance it will simply conduct back to the other prong and do no harm to your RV. Even if you shock it directly into a computer circuit board or something equally ridiculous as an accidental target, its more likely that the actual impact of the prongs will do more damage than the electrical discharge. The circuit impacted will more than likely just see it as a voltage spike or be completely unaffected. I make this very simplistic and usually don't get involved in electrical discussions on the forums, but I actually have a Bachelors in Electrical Engineering so I understand the issue fairly well. Doesn't mean I'm saying it cant happen that you could shock some system in your RV bad enough to hurt it, but the odds are you never will. Much more likely for lightning to damage your RV this way, be it while hooked up to someones power outlet, or just shocked in the woods unless you are sitting inside firing your Taser over and over again. <br><br> Tasers (which is a specific brand that shoots a dart dragging wires to shock someone) also require registry thru the Taser company in order to purchase. Every dart must be accounted for, this isn't law from what I understand, but is enforced by the makers of Taser itself.<br><br> Stun guns on the other hand work by pressing it against people and pushing the button, which Tasers are capable of when the prongs are not fired. Stun guns, and Tasers, require they shock the average person for 4-5 continuous seconds to be effective. A lot can happen in 4-5 seconds, and in the case of the stun gun if your hitting me with it you can bet I'm hitting you physically and trying to push it away from me. As one person I read on a self defense forum once said 'The person you scare the most with your little blue zapper is probably yourself.' Though I have found that dogs tend to be afraid of them, but wouldn't bet my life on it if a large hound was charging me.<br> <br> I am pro-gun, and definitely pro-self defense, even with Tasers, but they are not all that they are cracked up to be. Cops tend to be Taser happy and use them when they need not. The problem with this is that in even healthy people with no pace-makers etc, Tasers kill around 3 out of 1000 uses. <br> <br> So I'm not pressing you to change your mind about anything, but keep in mind that if you really need a defensive weapon, you probably should buy one that will effectively stop the attacker as quickly as possible. Might just anger that 300# biker with your stun gun, and make him be more vindictive when he gets his hands on you. <br><br> Bottom line is: No matter what you choose for self defense, you are to be held legally accountable if you use it. (So don't shoot anyone and claim I told you too, and I'm withholding names to protect the innocent...j/k)
