Excellent advise crandallbradley. A buyer should never complete the sale until he has done a very very thorough PDI (PreDelivery Inspection). It is also required that the dealer allows the buyer sufficient time to complete the PDI. If for any reason your dealer balks at such a request you would be advised to find another dealer. In fact he should be adamant about the buyer doing his own inspection as he should not want any rig being delivered unless it is 100%.
There are PDI links
HERE. It would not be a bad idea to present a copy of the PDI you will be using to your dealer in advance of your inspection. This way he has time to do his own PDI and make corrections before you get there BUT no matter what he says or does you still do your own inspection. NO IFS ANDS OR BUTS
