Shooting bench recommendations?

[norcalcyclist]

I am searching for a shooting bench. The range I shoot at is an informal area on BLM Property with no permanent benches. I was curious what others in a similar situation do for optic sighting and general target practice? RCBS Rapid Acquisition Shooting System (RASS) Shooting Bench? Caldwell Lead Sled on a Caldwell bench? DIY?

All help appreciated.
