I shopped around and talked to a lot of people and decided on the Cytech "Double Park". So, when I went to the VOI and saw one demonstrated, I was convinced that I had made the correct decision. The unit is very well engineered and the materials are first rate. With the options that I ordered, the price was about $3400. I have had it since 9/00, and my friends and I have used it extensively. I have lifted everything from a Viper to a Cummins Ram (had to fold in the mirrors on the Ram) and have had no problems with it. My only regret is that I did not get it sooner.
A word of caution: The unit is shipped in a single crate and is very heavy. (the ramps make up part of the crate). You have two options for getting it off of the truck: (1) Fork lift or front-end loader(I used a loader and chains) or (2) uncrate it on the truck and take it off piece-by-piece. If you do this, you will need sockets and wrenches up to about 1 1/4" (don't remember the exact size) and at least two strong helpers - more would be better. Oh yeah, just remembered, you also need snips to cut the metal packing bands. Any questions, feel free to email me or ask on the board. One more thing: save the nuts and bolts used in the crate, you will need them later.
