Probably just enough to keep the honest thieves out. Havent seen a RV yet I couldn't just stick a large flatblade screwdriver in the door jam and easily pry it open. All the aluminum supports bends rather easy and goes back into its original form...
We lock up everything but anything that is important to use always goes where we go in the truck...
Lots of the same info like this on the various posts you read about Rv Security...
Has nothing to do with going out of the country... If they want to get inside they will get inside real easy...
