There is no way of knowing if this will hold when trying to remove the lock as it looks like a portable grinder could remove it quickly . But here's my overall verdict: The lock fits well on my fifth wheel (2018 Grand Design Reflection), but it's easy to lose it. The key fits the lock well and locks it well, but I'm not sure how the heck you're ever going to change it. The powder-coated lock looks very good. Small plastic label attached, looks like it won't last long. On the other hand, if it flaps in the wind, it won't damage the paintwork of my motorhome. Overall 4 out of 5.
