Looked at these or the Apache 550. Don't know if they'll weather the abuse.
I do have an Apache 2800 full of RF test gear that has stayed safe over many miles of dirt roads bouncing around the bed of my truck.

The Apache absolutely does I have a 3600(?) for my yeasu ft710. Not one issue totally water and dust proof.
The 550 is a clear plastic, doesn't look at all like the bigger units which just look trustworthy, and so far have been for me.
