Avelers installed on Travel trailerutomatic le

Has anyone installed a automatic leveing system on your travel trailer? Did you install yourself and was it tuff or OK? Also did you go with a electric jack system or hydraulic? what was the brand and do you like it. I'm looking into the different systems for mine. I so far like the bigfoot system, as I have read a bad post about the bullseye system and them not returning the customers calls when they had trouble. I'm looking forward to the answers. Thanks so much in advance for your reply's.
