This is what I have and did a bunch of checking it out first and I normally keep my 70 Cuda on it:
http://www.liftsunlimited.com/prod-perfect-info.aspI have the XLT with the free extra width extension and it fits just inside a normal single wide stall this way. If you don't get the free extra width, good luck getting your truck on it and I have a full size 98 quad-cab Ram and this was the only lift I could find wide enough that I wouldn't have to fold my mirrors in on. This comes with a full 1 foot square base and I have had no problems with the concrete holding up and 6" is plenty. I have a 10'3" ceiling and have notched it out so I can fit the greenhouse of the 'Cuda up and in the ceiling and this allows me to go to the second highest notch and at that height, I can park my 05 Caravan underneath the 'Cuda.
I'm happy I bit the bullet and bought this lift and I know several people who have one including my Dad now. If you are going to be taking the ramps off on a regular basis, spend the money and get the aluminum ramps. I have the caster kit so I can roll the lift around in the garage but realistically, you probably don't need it and I would have been better off with the ramps instead.
I had my garage door reworked so it's snug to the ceiling and reused the existing opener and I don't have any concerns about hitting the car but I did center the lift in the bay so it's a bit farther ahead. Some people say you have to switch to a jack shaft opener but mine has been fine and the lift has been in place for 4-5 years now. I had this professionally done for less than $450 because I didn't want to tackle the door spring which I know people who have been hurt by.
I now fit 4 cars in a 3 stall but you will need to watch out and make sure the posts don't get in your way or you will still end up with a 2 car garage. You may need to compromise on the width and not be concerned about getting anything bigger than a car on it or you may lose the other bay.
The 4-post lifts are great for storage but a two post non drive on one is better if you are going to be working on the bottom of cars all the time but you can use the 4-post for that and more if you can live with the drive on portion being in the way. I do have two sliding jack trays so I can suspend the car on the lift and change tires or work on the rear-end - whatever.
Yes it is an investment but if you cannot build or get a bigger garage you'll be happy and you will find other things to do once you have it too that are so much easier - like detailing the underside, changing transmissions, exhaust, starter, whatever.
Oh yeah, if you have the bucks, they would build you a double wide lift too that would hold two cars but it's cheaper to get two lifts and more flexible that way and you could save some money by using a shared pump with disconnects. Probably not a big deal to you but they will work with you.
