Has anyone installed one of these on their trailer? If you did, was it the 3.0 or the 4.0 version? We're very intrigued by this device.
The main question is if it'll work on the new 21' trailers (2nd gen).
Out of all the measurements I did with the new trailers, I didn't measure the door lock! Window, yes; door handle, no. So, I'm hoping someone with the 2nd Gen 21 footer would be willing to do that for me.
From their site it states the following:
Common size handle: 3.5" wide by 4.25" tall
Common opening size: 2.75 wide by 3.75" tall by 1/5" deep
Thanks much! Greatly appreciate it.
