If you have a floor jack and jack stands...you can do it quite easily. I did mine in about 2 hrs or so in the driveway...by myself.
I compared my 2WD truck to a 4WD truck which had the AAL on it. It was harder to bounce my truck than the 4WD by jumping in the bed.
I used to slide a bit in the seat when making turns...now my butt stays put and I don't have to lean in the cab!
When I used to load the truck up...it sagged big time. Now with 700lbs of gear or so...it's almost level when driving down the road. When the time comes to move on from this T-100 and to another...I'm taking my Roadmaster off of this one and putting it on the next one.
