All I am saying is if the parts support from the OEM, parts manuals service manuals, not available especially on new stuff, technical & sales training, unrelaible equipment & parts availabilty dates ain't so hot - the local dealer will have a hard row to hoe. Ask any Clark dealer that survived the Clark Parts distribution move from Illinois to New Orleans (I stand to be corrected on that location but I'm pretty sure) and Cat dealer that lived thru the allocation of of equipment orders in the 1980's. Me thinks many Clark & Cat dealers took on other lines to survive.
It takes all working together with the a common objective and singing out of the same choir book to keep the customer happy & up & running.

Without question many techs (or sales or fiance or financial or rental or used equipment folks) with real life hands-on experience can out gun & hopefully teach the "factory experts".
