First TT Purchase, buying used?

Being one who likes to pinch pennies, I found a used Jayco SLX 184BH for sale that was only used about 5 times (I believe the owner, it's pretty spotless). Since the asking price is only $8,000 this seems like a great deal on a TT.

Now since the Jayco warranty only covers the first buyer, is this a good idea? Is there an extended warranty I could buy like Good Sam that will cover me in case I find things wrong that 5 trips didn't uncover...
