Stevem,
Congratulations on ordering your new mill. I'm sure you will enjoy it. I've had mine for more than 6 years and, like any piece of equipment in use, I've had maintenance and repairs to make. TK's support has always been great. I really appreciate Mike and Jason because they were there when my model (B-20) was the flagship of the fleet. Although my model has been superseded by newer versions, they still offer excellent support.
I had a example, just this week. I had a freak component failure.
I was working for a client and we were turning a massive bur oak log when the turner chain quit. A quick check showed that the set screw hole for gear on the hydraulic motor had blown out. I called Matt at TK, part was in stock. Clients went to unload and get lunch while I headed down to TK. The part was waiting for me when I got there. Wil made sure I had what I needed and $7 later I was headed back home. Back in business.
I am quite fortunate that I happen to live within driving distance (35 miles) of the headquarters for my brand of mill. If I call I can usually get someone right away who can answer my questions but I have learned a lot about my mill, and others, by going in and asking questions. I have also been able to overhear conversations with customers, both in person and their side of the phone. I have been ready to purchase parts, based on my diagnosis of the problem, and had one of them suggest an alternative cause for the symptoms - they are usually right on. I have seen the patience they have when walking someone through mechanical or procedural processes that they don't understand. Once or twice, it has been me.
Timberking, and WM for that matter, continuously improve their products, without changing model numbers. That is why it is important for them to identify your mill when you need assistance. Over the years my model has had several different engines, along with changes to clamps, loading arms, etc. You may hear people discuss an issue with a 1600 that your model doesn't have. In some cases the improvements are available for older versions. They even came out with new style guide rollers for my mill which hasn't been made for 5+ years.
You've invested with a top notch mill manufacturer, avail yourself of the training and support they provide. On the other hand, I don't envy you, or whoever, is going to haul that new mill 1800 miles.
