Bob, what brand are you affiliated with to bash the Crown? I think the 5000 has been covered. Someone needs to pipe up and tell how bad the Rayond Easi was when it first came out. You read the code and it tells you what card is bad. What the book does not tell you is that another card blew the first card. The next new card put in blows just like the first one.
A favorite troubleshooting method on the Raymond is to replace all the cards and send all the original cards back to the factory to find out which cards are bad.
Then there is the Raymond method of changing the parts just a little from year to year so you can't get the right parts with the parts book. You must call the dealer with the serial number to get the right part. This keeps you from swapping parts from one truck to another and having to go back to the Raymond for parts.
On the Crown's, one bad module does not blow another.
We could cover other brands of trucks, but when it comes to turret and reach trucks, if you want productivity and reliability, Crown and Raymond are the only brands to look at. All the rest play second fiddle. The operators will almost always choose a Crown or a Raymond when you demonstrate them against any other brands.
