I have had a Stable Lift for about eight years. I had hydraulic jacks. I paid more for me Stable Lift (new - $2,500) than I did for my TC. I installed it myself. I have no problems at all on how it functions, or where. Contrary to what nay Sayers may post, it works on pretty uneven ground. You will loose about 1-1/2" to 2" ground clearance if set up properly. For me, it does two things exceptionally well; very stable when off the truck, and eliminates the need for TC Tie-downs.
The Stable Lift will add weight to your TC, probably an additional 200 pounds overall. It could hinder off road travel, depending how rough the trail. Unlike the four individual jacks, it is secured very well to the TC, and I can say with mine I have slid my truck sideways when against a big rock. I would not suggest it be used for serious Off Road.
As for the appearance, that is an individual thing. Personally, I think a lot of trucks and/or TCs are ugly, with or without a Stable Lift. A lot of people have ugly kids, but they get used to them over time and love them anyway. :B I prefer a black Stable Lift. You can paint it to match your truck/TC.
There are many post on the Stable Lift. Do a search, and you can read for hours. Unfortunately, you will read posts made by nay Sayers that have never had a Stable Lift. Other than they contribute very little on the subject, but need to have something to say. This does not apply to all nay Sayers, but to most, in my opinion. There are a couple of people that have had a Stable Lift, and did not like them. Using the search, you can read their story.
