I bought my SP before I knew what the *#€• I was doing. Definitely not going buy the interior SP until that one bites the dust. As for the chains it is just a visual to make them think about it, my cordless reciprocating saw with the right blade can cut through 99% of the chains in under 20 seconds.
I could upload pictures of other security devices I use but it would take too long and with the knowledge just about every one of them is nothing more than a visual. Until I can hang my favorite sign by the TT when we camp it will have to do...."This trailer is protected by S&W 3 days a week, you guess which 3"
