I remember the L-type. It was a bit cramped inside, but it had a nice ride and the engine, 'Neptune', ran very smooth and was a high revver, inspite of its OHV configuration. The same engine was used in the Cimarron One-Tonner, if anybody here remembers it.

The Box-type started using the more powerful and sophisticated 'Saturn' which had OHC, but was noisier and less smooth than its predecessor, the Neptune.
