Well it is a forum and all you are gonna get are opinions, that what people have. I just know while some people swear by rustys, the average rustys lover just hasnt suffered their nasty stupid brake yet.
Now as for your statement of why buy the most difficult kit to install, has it occured to you that perhaps the easiest kit to install simply means they are doing it the cheap easy way? Sure TNT kits even RE LA kits can be a real PITA to install and require drilling/welding/asskicking, but I guarentee they are going to be a hell of a lot stronger and stable than some flimsy peice of powder coated crap that easily bolts on in a couple places.
Every Jeep is a bit different, deppending on little differences in components to the unibody flexing a bit differently. It helps a lot to be able to take that extra effort to put the stuff in the right place for YOUR jeep, not in the "average" position so it works with "most" jeeps, and then works only ok. A truck, particularly something with as much of an investment as you have in it, is not something that has any room for mediocrity. It needs to be safe and reliable whether you are a poser or not, lives deppend on it.
