RZR F/R weight bias

Does anyone know what the front/rear approx. weight bias is for a RZR ?
Mine is a 900 EPS 50" but I think it would be similar for any 2 seat RZR.
I ask this because I am looking for a solution to haul my machine in my truck.
I have seen on here members use a couple of different products which fit into the hitch receiver to effectively extend the bed of the truck and also take the load off the tailgate.
Both of the products I saw on here are no longer available.

I found this.

They claim it will support 1000#
I would use a couple of short ramps to bridge between the device and the truck bed.
I thought I could put some kind of struts from the unit to the ground while loading and unloading.
After the RZR is on it would only have to support rear of the RZR.
