I have one in my 02 and I love it. When driving on dirt roads with the manual hubs engaged, but still in 2wd mode it feels normal...meaning I don't feel the lokka trying to pull the wheels one way or another. I do 50-60mph on the washboards (in 2wd) and have no issues. When I do engage 4wd it's usually while driving over deep sand and I'm still doing around 20-30mph. In 4wd you can feel it try to pull to one side or the other but it's not too bad. A few times I've done some steeper climbs on loose/rutted hillsides and it climbs it easy. I also have an LSD so that helps a little, but I'm definitely a fan of the lokka.
