I have a customer interested in trading in his old Clark TM15 for something new so I decided to read the entire post... It got so far off the tracks, it was mostly a waste of time.

What is the criteria of a best 3 wheeler? Uptime, TCO, servicability?
Are we talking about a new unit or a few yr old unit?

As an independent shop, I would not touch a Linde (or variant) or a Jungheinrich. But I have select criteria to keep my customers happy.

I have had good experiences with the Crown, Yale and Hyster's. I find with proper maintenance I have relatively few unscheduled breakdowns and the parts pricing on all 3 can be reasonable.
I find the newer Toyota's to we weak in an abusive environment, gearboxes going etc. I have a few I look after and the downtime is terrible.
