With a single ended cylinder I am not sure how it would behave in regards to return to centre either... not that it should matter much for a rockcrawler, but with the POS system it returns to centre when driving just like any other regular steering setup.

the difference in force left/right isn't noticable. it is a c_ntload of force both ways, so you don't really pick it up. especially considering that force is always different one way to the other depending on sidehill or where the tyres are jammed up against, etc..
return to centre is based around a load reactive orbital, which doesn't work with a single ended ram due to the fluid unbalance in the system. for a straight out rockcrawler it is arguably better to have no return to centre, as you can point the wheels somewhere and forget about them while you concentrate on other things. that's more about personal preference and driving style though..
one thing i forgot to say before is you should limit the travel of your ram to suit your steering throw, standard steering stops don;t last long when the ram is trying to push the knuckles off the housing. tie-rods and rod ends don't cop it well either no matter how beef you make them.
