Rude and arrogant! We purchased our plow truck used and were having what appeared to be problems with the harness wiring. We called an inquired about having it checked out. We were told it would cost $1200.00! Not to repair anything, just to diagnose it. We were told that if we had purchased the plow from them we wouldn't be having a problem. Since we didn't, that was the price take it or leave it. We did not speak poorly to them in any way and were taken aback by the response. I just can't understand why someone would feel the need to treat another person, let alone a potential customer, that way. Will never do business with a company that treats people like that.
