**Q: How long is the arm on it?**
A: The arm on part# DH304 is 4" long

**Q: What screw lenght should i use to mount this item on my 2019 keystone cougar fifth wheel rv**
A: I used bolts through my cargo trailer wall for door hold back - no issues with wind.  Not sure on screw size - depends on your RV side material and mounting supports.  I'd make sure you have a board behind the siding you are screwing to so make your mount height dependent on a secure place to fasten to.
