I just thought for city use with a decent lift like you have, a sway bar is probably very beneficial. With my minivan, the results from removing the swaybar are almost negligable as far as being unsafe. You'd really have to "push it" to feel like you might roll. Mostly it leans a bit, like maybe an inch or two higher than what it probably should do, if it had a functional bar.

Have you thought of putting D-rings onto your S-10? I'm guessing your getting stuck because of ground clearance issues. How much does your S-10 have?

Do you have nice "redneck" tube bumpers on your K5?

If I could get a good job away from urban areas that's somewhere warm, I'd be on it "like a fat-kid on a smartie."

That's true, most minivans are pretty low to the ground from the factory. It all depends on the center of gravity height and how wide the wheelbase is. Old Jeeps are known for being top heavy and prone to rolling, for instance. My brother had a CJ years back - He put 44-inch Ground Hawgs, and a big lift on it. - unstable as hell. It looked like it would flip on a 5-mph turn sometimes. he took it up on some big sand dunes once and let the fronts hang off the edge. His wife was with him. he got out to take some pics and didn't notice he left it in neutral. The sand sarted shifting and it started to roll back down the big dune. His wife was screaming all the way down with him chasing it down the hill ! - Now there was a picture for ya!  His wife didn't drive stick, and didn't know what to do in the panic of the moment. He got lucky it didn't roll. It just got to the bottom and dug itself in when it hit. No one was hurt. He had to call a friend to pull his ass back out of the sand. He couldn't get any traction and it just kept burying itself past the axles.

I don't do much to my S-10. It's just fer gittin to work & back. It's got factory height on it. 2WD not 4X4 height. I try like heck not to get anywhere near a sandy shoulder any more. I don't see how I could put D-rings on it with those cheap plastic bumpers on it. I saw a video of some guy getting his car pulled out of a snow bank a while back. It ripped the bumper off and part of the back of the car too! New cars & trucks are all plastic.

I've thought about putting redneck bumpers on my off road beast. The other one has shiny new chrome bumpers. I replaced the old beat up chrome ones after years of beating on them off-road. I'm turning my old beast with the battle scars on the frame into a poor-mans show truck. I'm restoring it, a little at a time, but not to factory specs. I've had seveal guys jump out of their car or truck at a stop light and ask me if I wanted to sell my old Beast. It gets weird sometimes. I'm not parting with it. My wife can put a 'for sale' sign on it 5-minutes after I'm cold! She hates it!

I didn't mean attach a D-ring to the plastic bumper, lol. I was thinking of an attachment point on the frame, under the truck somewhere.  

There is none!  This ain't no 4X4 !  It's a street truck. There's absolutely nowhere to strap onto in front without cracking, or bending the cheap plastic bumper, or tearing up the steering or suspension. I finally bolted on a towing ball to the rear bumper ( the metal part in the middle, anyway ) so I can slap a tow strap to da *** and yank it off the sandy shoulder!  Like I said before: 2WD SUX !! ...at least on these little tonka trucks. I feel like I should get out and wind up the rubber band under the hood!  No offense to all the 2WD people out there with a real truck, and a real engine in 'em ! 

I own a 88 F150 4x4 with stock suspension. I removed both the front and rear sway bars and noticed a very small change in body roll on the street, however, I noticed a big difference off-road. I gained 3 inches of travel in the front and 5 inches in the rear.

As for it being unsafe, I personally don't think so. Older trucks didn't come with sway bars, and if you are worried about body roll on the street just remember to slow down, especially in the corners. Trucks arnt race cars, therefore they shouldn't be drove like race cars.
