thats a tight fit for the ranger in the back of your truck, fits like a glove.

 

those units look like a blast, they are a little wide for where we do most our riding though. i just think of how much more we could take with us. LOL

 

I own 2 sportsmans a 500 and a 700, as well as my Jeep. My jeep club maintains a local trail system for 4x4s. My wife and I took our quads over the worst of the trails. The trails include rocks tree roots logs and hills, a non modified jeep CJ or Wrangler cannot run these trails without damage (and a brainless driver). The 4x4 is seamless on the sportsman. My wife left hers on all the time. I turned mine off until I got to a place I couldn't go anymore in 2 wheel drive just to high light for me the difference...the front wheels just started pulling and over we went.
The best thing for anyone interested in a quad in my opinion is look up the local clubs, see what they run and where they run...their riding locations will probably match yours and they will know who the good dealers/service/parts places local are and which machines are best for the area.
