Downsizing, sort of?

I am not sure if I have buyers remorse, love the 2015, and have enjoyed it since 2015... life changes for sure. I am a high pressure welder by trade at an electric utility company, unfortunately our coal fired boilers have been recently shut down and am currently fighting with the company to reverse their decision on my job redundancy... Basically its move 1200KM away to another plant or take the buyout! so needless to say we are also dealing with moving onto my own mobile welding/custom weld shop company which I am sure many people can appreciate has its level of uncertainties. So compile this with the lack of towing KM I put on a year with it, makes it more and more difficult to justify.

while I know the 3rd generation "diamond in the ruffs" are very rare there still out there.

Just had a fellow contact me last night with a possible opportunity. Certainly not saying this is one of those diamond in the ruff's! higher KM for sure, but is it enough to be afraid of.
