Brand new rig, you have at least a year to decide. If you find the warranty work piling up in the first year, you MAY want to consider an EW.
We bought a 2003 DP in 2010. We got a 2yr Platinum Coverage EW from XtraRide. Not cheap but we were buying our first higher-end DP and did not want any unwelcome surprises. After the two years are up (in Sept), I will probably look into a Drivetrain-Only coverage policy. $15k for an engine or tranny replacment scares me enough to buy insurance. But that's just me!
