For a better product, HWH and Bigfoot both make hydraulic landing gear systems that level the 5er. You can get manual systems that require you to do the four leg extensions, via a switch panel, to make the 5er level. The other option is the automatic system where you just press a button and the 5er does its own thing to get level.
One difference between the HWH system and Bigfoot involves the hydraulic fluid cannister. HWH uses a central cannister while Bigfoot uses a cannister at each of the four legs.
To answer you other question, assuming that "RL" means "right" and "left" in terms of the electric leg motors, yes you can get them. I have them and they have two switches to operate them seperately.
