I am new to the board and was hoping I could get some help. 

I work for Ocean Rescue and we have 3 Kawasaki 610 4X4s.  The beds, floorboards, and some of the under side are rhino lined (not professionaly done) and they pull jetskis on a regular basis.  Each are washed down everyday and maintained regulary.  The average life span is 2 years (about 1300 hours) which seems kinda short to me.  I am not to experenced with UTV's so I don't know what to expect out of any other UTV.

We plan on getting a new UTV next year and I am hoping to get help in choosing and outfitting the new vehical.  Is there a UTV that you would consider a better choice and what modifacations could be made to get some more life out of it.  I understand that the Kawasaki 610 is one of the cheaper UTVs but would a more expensive UTV last longer.  Rust from the salt and abuse of everyday use is the main problem, so is there a better way to protect it from the elements.

Any help would be greatly appretated.
