OP, there are no “safety” issues with either one of them to be cautious about. Just use them per the instructions and you will be fine.
The Andersen is fine
The Pullrite is fine
A regular fiver hitch is fine.
There are arguments about which is the best... But from the most basic fifth wheel hitch (Say the ProSeries 15k) to the most expensive (Say the Hensley) they are all safe is used per spec and per instructions.
Some are smoother than others, but they are all safe.
Pucks vs rails is simply preference. One is not more secure than the other. I don’t care what anyone says about that. They are all safe.
Thanks!
